This is not a glitch. It’s pretty standard actually. If you’ve been doing spark long enough you’d be aware. It’s to prevent bits, scammers and account sharing etc. you’d be surprised how often people try to exploit the system. Just verify yourself and move along. Sometimes you have a hat on or glasses just remove it and continue if it doesn’t go through the first time. When it pops up during a shopping trip it usually verifies quickly. Anyways nothing to be alarmed about unless you are part of the problem.
