    authPrompt: Bump the user verifier timeout when wiggling the message
    
    Wiggle may make the error message to be visible for less time so provide
    the auth prompt an API to increase the timeout to be used for showing a
    message in some cases.
    
    This could be reworked when we'll have a proper asyn wiggle function so
    that we could just make the user verifier to "freeze", then await for
    the wiggle transition to complete and eventually release the verifier.
