LastPass password manager users have been experiencing significant login issues starting early May after being prompted to reset their authenticator apps.
I switched from LastPass to Bitwarden, years ago now, and the whole process took roughly 5 minutes. I'm not sure if something has changed since then, or if it's more complicated to switch to something other than Bitwarden, but my experience is that it at least can be simple.
KeepassXC and sharing the databases between devices with any sync tool is the best bet for me. Used it since I started using password managers and I will never understand using any online service for this.
