The data structure used to help initialize an assertion for a second factor entity to the
Firebase Auth/CICP server. Depending on the type of second factor, this will help generate
the assertion.
Creates a TOTP secret as part of enrolling a TOTP second factor. Used for generating a
QR code URL or inputting into a TOTP app. This method uses the auth instance corresponding
to the user in the multiFactorSession.
