Multi-factor authentication (MFA), also known as two-factor authentication (2FA), is a authentication method which requires an additional step to access your account. In the case of Platform One SSO, it's utilizing a six digit code that is generated by a separate app typically on a mobile device. There are many different MFA apps to choose from but some of the more common ones are Google Authenticator and Authy, both of which can be downloaded from the Apple or Google Play app stores.
The instructions below will guide you through setting up MFA using Google Authenticator on an Apple iPhone. If you're using a different MFA app or device, the steps will be slightly different.
The most common issue users have is the "Invalid authenticator code" error. Performing the following steps should resolve the issue.
