If they change/rebrand the login he’s screwed. Just use a password manager people.
I’ve been thinking of starting to use one more and more, is there any you would recommend? Are all the good ones a paid service? And my biggest concern is someone getting into the password manager itself, is that something that I should worry about?
I’ll second the other comment suggesting KeePass, but the biggest issue I had with it was syncing the database across devices. Ultimately I stored it in OneDrive, but it occurred to me that at that point it wasn’t much different to a cloud password manager, which I especially didn’t trust.
I now self host a Vaultwarden instance from my Raspberry Pi, and that works perfectly for me, but it does require a bit of Linux experience and a spare device to run the server.
I don’t trust a service for my passwords so I’d rather trust an open-source software.
Try KeePass, it runs both on a PC as well as a phone so just carry your encrypted passwords with you.
Edit: And passwords aren’t enough, use multi-factor for services that offer it. Preferably via an app instead of SMS.
