Deffo focus on ensuring the stuff that matters is properly secured (decent passwords tiered appropriately, MFA). Far better use of your time.
Yeah, I’ve got a load that have been nagging me for ages, the new Passwords app certainly makes things a lot easier to see and use – a lot of the flagged ones go back some years, I can’t remember what they were used for now!
I’ll go through and cull them over time, any that might be an issue I’ll upgrade them. I do try to use passwords generated by the OS, but there are some sites that just won’t accept them, so I have to spend time fannying around trying to create something that works but isn’t obvious to guesswork.
