How to set up two-factor authentication

What is two-factor authentication?

Two-factor authentication, or 2FA, is an extra layer of security you can apply to your MailerSend account to ensure that you’re the only person who can log in to your account, even if somebody else obtains your password.

With 2FA you will be required to enter a randomized 6-digit code every time you log in, preventing anyone else from accessing your account.

How to turn on two-factor authentication

1. Use the top right account menu to navigate to the My profile page.

5. Scan the QR code in your MailerSend account.

6. Enter the generated code into the field provided in your MailerSend account.

7. Click Set up.

Note: Each recovery code can only be used once. If your mobile device is lost, it’s recommended to log in with a recovery code, turn off 2FA and set it up again using a new device.

How to turn off two-factor authentication

To turn off two-factor authentication:

1. Use the main dropdown menu to navigate to the My profile page.

2. Toggle Two-factor authentication off.

3. Enter your password and click Turn off.

Turn off 2FA

Note: Once 2FA is turned off, the codes being generated in your Google authenticator app (and your recovery codes) will no longer work. If you wish to turn 2FA back on (recommended), simply scan the QR code again and repeat the steps above to set it back up.
