JavaScript: Get Authenticator Assurance Level

Returns the Authenticator Assurance Level (AAL) for the active session.

• Authenticator Assurance Level (AAL) is the measure of the strength of an authentication mechanism.
• In Supabase, having an AAL of aal1 refers to having the 1st factor of authentication such as an email and password or OAuth sign-in while aal2 refers to the 2nd factor of authentication such as a time-based, one-time-password (TOTP) or Phone factor.
• If the user has a verified factor, the nextLevel field will return aal2, else, it will return aal1.
