I can not find it so I assume it has been introduced in newer version than the one I am using.

I think that when I am having link like https://lemmings.world/post/10530999 or knowing a title of the post, i can not discover in which community it has been posted… When I check same number of post on different instance: https://lemmy.ml/post/10530999 it does NOT work. Yet the search works: https://lemmy.ml/search?q=10530999 is there no other/easier way than opening one big instance after another (for example from the list https://lemmyverse.net/?order=posts&open=true ) and use search like that?

OF opinion: good not to be adicted to it or to anything actually.

I have been told that it is not safe to enable 2FA and use Pass as an authenticator. For Proton account 2FA I am using not only Pass but also KeePassXC as a backup solution (for the case when Pass logout and requires 2FA code in order to login - and in such a case you can not get the 2FA code out of Pass - chicken-egg problem). Yet when using Pass desktop app, maybe logout issue is minimized (it remember my password across reboot and paid Pass is said to work offline).
