SMS as MFA Verification Method
Last updated April 05, 2021
SMS as a MFA verification option is no longer available to new users. Users that currently rely on SMS for MFA verification should expect that this option will be available only for a limited time. You will be notified once a specific date of for discontinuing SMS support has been determined.
Users with a mobile phone number registered with Heroku as a 2FA backup option prior to 2020 have the option of using SMS as a MFA verification option when their Authenticator app is not available.
However, in order to protect user accounts from the Security risks associated with use of SMS, Heroku is not offering SMS as an MFA verification option for any new users and plans to discontinue it for all current users.
Heroku will provide ample advance notice prior to discontinuation of SMS as MFA verification option.
