This. I want a password/passkey/auth and bookmark manager that work across platforms and devices.
Well, then I’ve gotta bust your balls here and tell you to step away from the Win98 machine, because that’s been around for some time.
Even secure, privacy-respecting versions!
Don't you have this already? Chrome and Firefox both have these. Devices have solid password manager integration, I use mine across 3 OSes and who knows how many devices.
