At this point NOT using a password manager is absolutely insane from a security perspective. Password managers not only make your life easier, but if you use them correctly, you can setup each service with its own dedicated and complex password. Good luck doing that without one!
absolutely. My average password is something like "!^knqopLy4qiVa@2msZ8nLxjjz". while it can be occasionally annoying copying it to something new (for example, when i log into my VR headset after factory resetting it), its more than worth it for security.
For any password I might have to type in, I usually generated a series of strings. While not technically not as secure, it's pretty damn good and easier to type in. But I'd say 98% of my passwords are 20-100 characters of random gibberish. I also use 2FA with Aegis on as much as I possibly can. When I was using google authenticator, it got extremely annoying with 30 accounts with no search feature and random ordering. Aegis has made having even more a breeze. Now I have no problem adding every account possible with 2FA. (Sorry apple users)
You're locked into those platforms if you use built-in password managers. Personally I don't like the idea of Google or Apple having all my data by using their proprietary password managers.
Interoperability between platforms, and lack of trust of giant tech corps, for me. I'm not all in the apple garden entirely, and I can swap around as needed. Google nor MS care about privacy, and apple likely only does for optics reasons.
There's ways, I don't use chrome, but I do use Vivaldi which can use the same plugins. Use whatever works for you though, I think that's what's most important!
