How to force the Auth0 user to always enter his password to log in with Auth0 instead of using "Last time you logged in with " button?
If you are using the Auth0 Lock Widget, then there is a rememberLastLogin option that should suppress the "Last time you logged in with" button.
From the docs:
rememberLastLogin {Boolean}: Determines whether or not to show a screen that allows you to quickly log in with the account you used the last time when the initialScreen option is set to to "login" (the default). Defaults to true.
