It was discovered that version of phpMyAdmin prior to 4.9.8 and 5.1.2 are
subject to a bypass of two-factor authentication.

There is a sequence of actions a valid user can take that will allow them to
bypass two factor authentication for that account. A user must first connect to
phpMyAdmin (presumably using their two factor authentication method) in order
to prepare their account for the bypass.

Note that a user is still able to disable two factor authentication through
conventional means; this only addresses an unintentional security weakness in
how phpMyAdmin processes a user's two factor status.
