With two-factor authentication, only you can access your account on a trusted device or the web. When you want to sign in to a new device for the first time, you'll need to provide two pieces of information—your password and the six-digit verification code that's automatically displayed on your trusted devices or sent to your phone number. By entering the code, you're verifying that you trust the new device. For example, if you have an iPhone and are signing into your account for the first time on a newly purchased Mac, you'll be prompted to enter your password and the verification code that's automatically displayed on your iPhone.
Because your password alone is no longer enough to access your account, two-factor authentication dramatically improves the security of your Apple ID and all the personal information you store with Apple.
Once signed in, you won’t be asked for a verification code on that device again unless you sign out completely, erase the device, or need to change your password for security reasons. When you sign in on the web, you can choose to trust your browser, so you won’t be asked for a verification code the next time you sign in from that computer.
A trusted device is an iPhone, iPad, or iPod touch with iOS 9 or later, or Mac with OS X El Capitan or later that you've already signed in to using two-factor authentication. It’s a device we know is yours and that can be used to verify your identity by displaying a verification code from Apple when you sign in on a different device or browser. An Apple Watch with watchOS 6 or later can receive verification codes when you sign in with your Apple ID, but cannot act as a trusted device for password resets.
A trusted phone number is a number that can be used to receive verification codes by text message or automated phone call. You must verify at least one trusted phone number to enroll in two-factor authentication.
You should also consider verifying an additional phone number you can access, such as a home phone, or a number used by a family member or close friend. You can use this number if you temporarily can't access your primary number or your own devices.
A verification code is a temporary code sent to your trusted device or phone number when you sign in to a new device or browser with your Apple ID. You can also get a verification code from Settings on your trusted device.
A verification code is different from the device passcode you enter to unlock your iPhone, iPad, or iPod touch.
You can follow these steps to turn on two-factor authentication on your device. Learn more about the availability of two-factor authentication.
You might be asked to answer your Apple ID security questions.
If you're using macOS Mojave or earlier:
Some Apple IDs created in iOS 10.3 or macOS 10.12.4 and later are protected with two-factor authentication by default. In this case, you see that two-factor authentication is already turned on.
If you have an Apple ID that's not protected by two-factor authentication, some Apple web sites might ask you to update your account.
Two-factor authentication significantly improves the security of your Apple ID. After you turn it on, signing into your account will require both your password and access to your trusted devices or trusted phone number. To keep your account as secure as possible and help ensure you never lose access, there are a few simple guidelines you should follow:
You can manage your trusted phone numbers, trusted devices, and other account information from your Apple ID account page.
To use two-factor authentication, you need at least one trusted phone number on file where you can receive verification codes. Consider verifying an additional trusted phone number other than your own phone number. If your iPhone is your only trusted device and it is missing or damaged, you will be unable to receive verification codes required to access your account.
If you want to add a phone number, click Add a Trusted Phone Number and enter the phone number. Choose to verify the number with a text message or automated phone call, and click Continue. To remove a trusted phone number, click next to the phone number you want to remove.
You can view and manage a list of your trusted devices on iOS, macOS, and in the Devices section of your Apple ID account page.
On iOS:
On macOS Catalina or later:
On macOS Mojave or earlier:
On the web:
The device list shows the devices that you're currently signed in to with your Apple ID. Select a device to view device info like the model and serial number. Below that you can see other useful information, including whether or not the device is trusted and can be used to receive Apple ID verification codes.
You can also remove a trusted device by selecting Remove from Account from the device list. Removing a trusted device will ensure that it can no longer display verification codes and that access to iCloud, and other Apple services on the device, is blocked until you sign in again with two-factor authentication. If you need to find or erase your device before you remove it from your trusted device list, you can use Find My iPhone.
With two-factor authentication, you need an app-specific password to sign in to your account using third-party apps or services such as email, contacts, or calendar apps not provided by Apple. Follow these steps to generate an app-specific password:
After you generate your app-specific password, enter or paste it into the password field of the app as you would normally.
Need help? You might find the answer to your question below.
You can reset or change your password from your trusted device or browser when you follow these steps.
If you're using macOS Mojave or earlier:
If you don't have access to an iPhone, iPad, iPod touch, or Mac, you can reset or change your password from iforgot.apple.com.
If you're signing in and don’t have a trusted device handy that can display verification codes, you can have a code sent to your trusted phone number via text message or an automated phone call instead. Click Didn't Get a Code on the sign in screen and choose to send a code to your trusted phone number. You can also get a code directly from Settings on a trusted device. Learn how to get a verification code.
If you use iOS 11.3 or later on your iPhone, you might not need to enter a verification code. In some cases, your trusted phone number can be automatically verified in the background on your iPhone. It’s one less thing to do, and your account is still protected with two-factor authentication.
If you can’t sign in, access a trusted device, reset your password, or receive verification codes, you can request account recovery to regain access to your account. Account recovery is an automatic process designed to get you back in to your account as quickly as possible while denying access to anyone who might be pretending to be you. It might take a few days—or longer—depending on what specific account information you can provide to verify your identity.
If you generated a recovery key, you can use your recovery key to regain access to your account instead. Learn more about using a recovery key.
No. With two-factor authentication, you don't need to remember any security questions. We verify your identity exclusively using your password and verification codes sent to your trusted devices and phone numbers. When you enroll in two-factor authentication, we keep your old security questions on file for two weeks in case you need to return your account to its previous security settings. After that, they're deleted.
Apple Support can answer your questions about the account recovery process, but can't verify your identity or expedite the process in any way.
For the best experience, make sure that you meet these system requirements on all of the devices you use with your Apple ID:
Yes. Any Apple ID that meets the basic system requirements can enroll in two-factor authentication. Learn more about who can use two-factor authentication.
When you sign in on a new device, you’ll get a notification on your other trusted devices that includes a map showing the approximate location of the new device. This is an approximate location based on the IP address the device is currently using, rather than the exact location of the device. The location shown might reflect the network you're connected to, and not your physical location.
If you know you’re the person trying to sign in but you don’t recognize the location shown, you can still tap Allow and continue signing in. However, if you ever see a notification that your Apple ID is being used to sign in on a new device and you're not the one signing in, tap Don’t Allow to block the sign in attempt.
If you use two-factor authentication with devices running older OS versions—like an Apple TV (2nd or 3rd generation)—you might be asked to add your six-digit verification code to the end of your password when signing in. Get your verification code from a trusted device running iOS 9 and later or OS X El Capitan and later, or have it sent to your trusted phone number. Then type your password followed by the six-digit verification code directly into the password field.
If you already use two-factor authentication, you can no longer turn it off. Certain features in the latest versions of iOS and macOS require this extra level of security, which is designed to protect your information. If you recently updated your account, you can unenroll within two weeks of enrollment. Just open your enrollment confirmation email and click the link to return to your previous security settings. Keep in mind, this makes your account less secure and means that you can't use features that require higher security.
Yes. Two-factor authentication is built directly into iOS, macOS, tvOS, watchOS, and Apple’s web sites. It uses different methods to trust devices and deliver verification codes, and offers a more streamlined user experience. You need two-factor authentication to use certain features that require improved security.
If you already use two-step verification and want to update to two-factor authentication, learn how to switch to two-factor authentication. If your account isn't eligible for two-factor authentication, you can still use two-step verification to protect your information.
In recent releases of IE, Edge, Google Chrome, Firefox, and latest Citrix Workspace App clients many of the issues mentioned below have been resolved.
By default, the OS (Windows, Mac, Linux) should automatically set how to open '.ica' files when trying to launch any resource via Citrix Workspace or Citrix Storefront via the Web Store if the Citrix Workspace App is installed properly.
Confirm Citrix Workspace App is installed or use Citrix Workspace App for HTML5 ('Web Browser' option) instead.
If you continue to encounter this behavior please review the steps outlined below.
There can be a number of resolutions to the issue including but not limited to the following:
Install the latest Citrix Workspace App version which can be downloaded here: Download Citrix Workspace App
When clicking on an application or desktop to launch via Citrix Workspace or Citrix Storefront on an Internet Browser (not within Citrix Workspace App) and an '.ica' file shows in the download bar on the bottom left please follow these steps to automatically open said file:
ICA file is downloaded during the process. After the ICA file is downloaded, enable the browser to open similar files automatically.
Note: Instructions below are similar for other OS's when using Google Chrome, Firefox, or Edge Browsers.
On Windows computers, go to Control Panel > Settings > Apps > Default apps > Choose default apps by file type
Under Name, find .ica file type.
Ensure that the current default is set to Citrix Connection Manager. If not, click Change program and choose Citrix Connection Manager.
Note: Connection Manager is the wfcrun32 file located as C:Program Files (x86)CitrixICA Clientwfcrun32.exe
Remove or disable any third party browser based Adware software that could be interfering with the successful launch of the ICA file. Restart the browser after removing these software and try again.
If you are using Internet Explorer, click Tools > Internet Options > Advanced tab and clear the option “Do not save encrypted data to disk.”. This option should be cleared because the dynamic files are stored in the Temporary Internet Files folder. When applications are clicked, a file is downloaded to the folder, then launched using MIME type. If access to the folder is disabled or not available, the process cannot occur successfully.
Add the site to the Trusted sites list if using Internet Explorer browser using the following steps:
Go to Tools > Internet Options > Security tab > Sites
In the Add this website to the zone field, enter your organization's website and click Add.
Repeat this for the .com, .net, .org, or .gov Web site addresses of your organization to allow the use of the ActiveX ICA client object for the launched connection to be automatically accepted.
Note: It might be required to also add any additional subdomain.domain.com URLs to the Trusted sites list in the Security tab setting if still experiencing unwanted prompts.
Configure Internet Explorer as follows to allow successful application launching:
Disabling ActiveX filtering globally:
Click Gear icon, select Safety, de-select ActiveX Filtering. Alternatively, press Alt key and click Tools menu (ActiveX filtering is enabled if a “tick” appears next to it and is disabled if the “tick” disappears).
Or
Log on to the Web Interface site and attempt to launch an application. At the end of the address bar a blue warning sign appears, indicating filtered content.
Click the blue warning sign and select Turn off ActiveX Filtering.
Add the site to the Trusted sites list: In the Security tab of Internet Options, add the Web Interface site to Trusted Sites list to allow the use of the ActiveX ICA client object for the launch.
Or
Disable the MIME filter: Rename the following registry key: HKEY_CLASSES_ROOTPROTOCOLSFilterapplication/x-ica
Log off and close window then restart the browser after making this change.
Configure Internet Explorer as follows to allow successful application launching:
There can be a number of reasons for the issue including but not limited to:
CTX139939 - Microsoft Internet Explorer 11 - Citrix Known Issues
CTX200889 - Receiver for Web Workaround with NPAPI Support Removal in Google Chrome
CTX126653 – Citrix Online Plug-in for Windows with Internet Explorer 9 Support
