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. Verifying a phone number is a required part of the setup process to ensure you have a backup method of getting logged in if you lose access to a device using app authentication.
Once you have your phone number set up, you can proceed so set up app authentication, if you prefer to use an app for 2FA.
After the setup process is complete, you will see a confirmation page that includes your backup codes. It is very important to save these backup codes in case you need them in the future to log into your account.
Make App authentication the primary method
To set app authentication as your primary method, click Manage next to Two-factor authentication in the security section of your profile. Then click Set as primary for App authentication.
Retrieving Backup Codes
Viewing Users’ 2FA Settings
- 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 or an SMS text to get logged in.
