It's definitely a leap to use a password manager. Actually it's a pain in the ass. but it's so worth it.
Passwords aren't going away any time soon so this is the only safe options for the near future. Get onto it.

I've used pretty much every password management tool out there and as someone who is using multiple devices on different OSs, Dashlane is excellent. Customer support is great, the product just works and kept me same from Equifax 😅
I've used every password manager on the market, and finally settled with Dashlane. I got the 5 year plan, because it's so awesome. It works well, and I really have nothing bad o say about it at all, other than he Chrome extension being buggy and you need a small workaround to install on Chromium based browsers like Vivaldi. But I highly recommend it. I don't know why it isn't more popular.
