Apple is set to require app-specific passwords for third-party apps that connect with iCloud starting on Thursday, June 15. The requirement is detailed in a notice the company is setting out to users via email.
“Beginning on 15 June, app-specific passwords will be required to access your iCloud data using third-party apps such as Microsoft Outlook, Mozilla Thunderbird, or other mail, contacts and calendar services not provided by Apple,” the company says in the notice. “If you are already signed into a third-party app using your primary Apple ID password, you will be signed out automatically when this change takes effect. You will need to generate an app-specific password and sign in again.”
To generate an app-specific password, you must first enable two-factor authentication for your Apple ID. Beginning with iOS 10.3 and later, two-factor authentication is set by default.
To generate an app-specific password for each iCloud-connected third-party app, you need to log in to My Apple ID and click “Generate App-Specific Password” under Password & Security. Use the generated app-specific password in the app’s password field just like a normal password.
You can have up to 25 active app-specific passwords at a time, any or all of which you can revoke if necessary.
