If the user cannot access their email address, an email reset may be requested using auth.resetLoginEmail.

To change the login email after login, pass emailVerifyPurposeLoginChange as purpose, following the exact same Google ID/Apple ID/email code login flow as above: on success, the account.verifyEmail method will return an account.emailVerified constructor.

Sign in/sign up

Sign in/sign up

When user enters verification code, the auth.signIn method must be used to validate it and possibly sign user in.

If the code was entered correctly, but the method returns auth.authorizationSignUpRequired, it means that account with this phone number doesn't exist yet: user needs to provide basic information, accept terms of service and then the new user registration method (auth.signUp) must be invoked.

2FA

When trying to sign in using auth.signIn, an error 400 SESSION_PASSWORD_NEEDED may be returned, if the user has two-factor authentication enabled. In this case, instructions for SRP 2FA authentication must be followed.

To set up two-factor authorization on an already authorized account, follow the SRP 2FA authentication docs.

Test Accounts

Each phone number is limited to only a certain amount of logins per day (e.g. 5, but this is subject to change) after which the API will return a FLOOD error until the next day. This might not be enough for testing the implementation of User Authorization flows in client applications.

There are several reserved phone number prefixes for testing that your application handles redirects between DCs, sign up, sign in and 2FA flows correctly. These numbers are only available on Test DCs (their IP addresses for TCP transport are available in API development tools panel after api_id was obtained, URI format for HTTPS/WebSocket transport).

If you wish to emulate an application of a user associated with DC number X, it is sufficient to specify the phone number as 99966XYYYY, where YYYY are random numbers, when registering the user. A user like this would always get XXXXX as the login confirmation code (the DC number, repeated five times). Note that the value of X must be in the range of 1-3 because there are only 3 Test DCs. When the flood limit is reached for any particular test number, just choose another number (changing the YYYY random part).
