Update Phone Number or Alternate Email Address for Multifactor Authentication (MFA)

Use this guide to update your existing phone number or personal email address used for Multifactor Authentication (MFA) or password reset. This guide applies only if you already have an authentication method set up.

Important: A personal email address does not count as a second authentication method as it is not used for sign‑in verification. It is used only for password reset purposes.
