@jonah@AIBrain@doomy@protonprivacy In fact, people are significantly more likely to forget a password than to forget their email address.
And if they have multiple addresses and don't remember which they used, they can try all of them.
As I said, this is a privacy vs. convenience trade-off.
Other apps do this (require recovery email to be verified by user before it can be used for recovery). Proton would not be breaking new ground here.
