I'm not sure how it is on iOS, but I've been using firefox as my password maanger on android. It's a trivial change in the settings and works across all apps as well.

I also recommend it to my friend group, as they can use firefox with uBlock Origin, and also have their passwords synced.

Yep, since Android 12 I think you can set Firefox as your main password manager.

It's genuinely delicious

dd can do seek, skip, re-block. It's unusual to need the features but they exist for good reasons. I used dd to transfer 4.1BSD release tapes to a vax 11/720 via rl02 10meg pack and reconstruct the chunks on the receive side, long ago.

ddrescue will do this for you automatically to recover from a bad block.
