[Usability] Link-through to specific wallet provider to decrease login times

[FantasticoFox]

We would like to 'quick' link directly to the 'Metamask' Wallet for login to skip 3 clicks and wait times.
Best would be if there is a 'deterministic link' which allows to target all the different selection options, so we can link into that stage of the selection wizard.

This will help to decrease login times and user-experience.
