I had an security idea where the welcome message would be a sha512 hash, created with todays date + time (15 minutes interval) + pre randomly created static salt.
When you are about to login you check the hash against a hash you created on your phone.
If it's the same hash, you know it's your computer and not a honeypot someone put there to get your password.

@fabiscafe
How do they work?
They don't leak any data if you plug them in a honeypot device and use them?
