How do I use two factor authentication (2FA)?
Two factor authentication(2FA) adds an additional step to logging in for increased security. You can use either SMS text messages to your phone number or an authentication app we support to retrieve a code you will need for logging in to your Postmark account. 2FA can be enabled by all user types and is recommended for security.

- Save your backup codes
- We don't provide an option for using a backup number with SMS authentication. This means that if you change your phone number, you will need to use a backup code to get logged in and change your 2FA phone number.
- If you are traveling and unable to receive SMS messages, use a backup code to get logged in.
- If you are using app authentication and have a new phone without the app installed, you will need to use a backup code to get logged in.
