Highlights

- Activating/deactivating applies to all account users.
- Account users at the time of activation will be permitted to log in and prompted to set up 2FA at their next login.
Admin: Managing 2FA
Only an admin user can activate, reset, or deactivate a user's 2FA settings.
Activate
If an admin activates Google Authenticator and SMS verification, account users can choose which method they prefer to use.
Note
SMS verfication depends on SMS success rates, which vary by mobile carrier and country. Therefore, we strongly recommend enabling both SMS verification and Google Authenticator to avoid being locked out due to failed SMS delivery.
To activate 2FA:
- From the top bar, open the account menu (email address dropdown) > Security center.
- In the Enhanced login security section, click Configure login method to access the Login security page.
- In the Two-factor authentication (2FA) section, activate the toggle for Google Authenticator and/or SMS verification.
Reset
For accounts using 2FA, there may be occasions on which you need to reset a user’s 2FA. Note that after reset, Google Authenticator is the default 2FA login screen.
To reset a user's 2FA:
- In the menu bar, click on the email address dropdown.
- Select User management.
- On the Users tab, click the menu options
on the far-right side of the user’s row.
- Select Reset 2FA from the menu.
Note: An admin can reset any other admin's 2FA other than their own or the account owner's. To reset the account owner's 2FA, contact the AppsFlyer Support team.
Deactivate
If 2FA is deactivated, account users will log in using only their username and password.
To deactivate 2FA:
- From the top bar, open the account menu (email address dropdown) > Security center.
- In the Enhanced login security section, click Configure login method to access the Login security page.
- In the Two-factor authentication (2FA) section, deactivate the toggle for Google Authenticator and/or SMS verification.
