Yes, use a password manager. Unless you're a password savant that can remember every character he's typed, you'll either be re-using passwords (a big no-no), or storing them somewhere. It's much more secure to remember one strong password and use randomly generated passwords everywhere.

I use Lastpass. They have synchronization across devices on their free tier, which is awesome. You can automatically import passwords from Chrome or Firefox. They even have a "security challenge" that will show you what repeated and weak passwords you're using. Lastpass also has some degree of automatic password reset on popular sites, which works pretty well.

Hi, this has been asked before a while ago so I thought I'd link you to what was answered back then to get you started:

I give a vote for 1Password on Mac but on Linux I quite like Pass.

Try Avast Passwords: https://www.avast.com/passwords

It is free and it covers all platforms (Windows, Mac, iOS and Android). Even synchronization between devices is for free.

I have around 100 accounts saved in my password manager so it is impossible now to be without passw. manager. I'm using SaferPass > www.saferpass.net
