There are a few ways to regain access to your Stripe account if you no longer have your authorized two-step authentication device (for example, your mobile phone) and/or backup code.

If you do not have your backup code or your authorized two-step authentication device

If you are the account owner, submit a request through the account recovery form. For security purposes, you will be asked to provide detailed information about your account OR upload a government issued ID to confirm your identity. Once we confirm your identity, you’ll be able to sign in using your password.

If you are NOT the account owner, the primary account owner or an account administrator can help solve this issue for you! One of these folks will want to simply reset your two-step authentication from the Stripe account in the Team settings page; This will send an email to you with a link to regain access to your account.

If you still have your backup code

• Sign in with your email address and password.

• Click Sign in another way when prompted to enter your two-step authentication code.
  

• Click Use your backup code and enter your password and backup code to disable two-step authentication. (The backup code was shown to you when you set up two-step authentication or if you regenerated a new one.)
