Auto login URL's
Basically this: Make it possible to create URL's that automatically redirects to my inbox, without the need to enter any of my credentials.
Obviously, it should be possible to restrict the URL in various ways; possibly including:
1. IP restriction: Only whitelisted IP's may utilize the URL.
2. Remote deletion: Various convenient options to remotely render individual URL's (or all) useless.
3. Max uses: Set a maximum number of daily logins, and shut it down if this number is exceeded.
4. Timeout: Set a maximum life time on the URL, rendering it useless after that time has passed.
The resulting inbox probably shouldn't have access to the options panel without proper authentication, only basic mail usage.
I'm aware that ProtonMail is encrypted using our own personal (zero knowledge) key, but wouldn't it be feasible to embed the encrypted key in the URL (using a two-way encryption), then decrypting it on the server, then decrypting the inbox?
I am by no means a security expert, so I apologize if this suggestion's beyond crazy.
