"Verify this login"

### Steps to reproduce

1. Log into a new session in iOS
2. [get distracted by something while the login happens for more than 2 minutes]
3. There is no way to re-trigger the verification on another device, the only options I have are "Use Security Key" or "Skip"

### What happened?

### What did you expect?

After two minutes to see something which says "verify with another device" to re-trigger the verification process

(Also, "If you can't access an existing session" message feels like it's out of place and not in flow with the button above it)
