By registering multiple multi-factor authentication methods, you can log in with another method even if one authentication method becomes unavailable.
For this reason, we recommend setting up multiple multi-factor authentication methods.
In addition, FIDO authentication (such as Windows Hello) allows you to log in smoothly because password input is not required.
For instructions on how to set up multi-factor authentication, please refer to the linked page.
