Password manager-less life with notebooks and reused passwords is life in the stone age. If you or anyone you know isn't using one, get on bitwarden.
Everyone knows why password manageras are absolutely essential, but here's an often neglected perk: I can list every site I ever signed up to. Wanna delete some old accounts? "Did you sign up to X yet?" Simples.
I've started using LibreTube, its a lot like NewPipe, but I much prefer the UI. Check it out! (Its in F-Droid, of course)
