Most people would use a password manager for this, since trusting any webbrowser's built-in password handling has been proven to be a bad idea. Now, I prefer to use password manager manually, so I know exactly when passwords are used, but some people like to have them autofill using an extension. I just don't like browsers to have direct access to my password DB.
Bitwarden and
KeePassXC are on my short list, but lots of people prefer to pay money to use password managers from others, like 1Password or LastPass. Some sites, like banks are known to block automatic password entry or to add steps like call-backs before the allow access. My bank will provide a small hardware token with a changing password every 60 seconds. Just be cautious if a bank or other financial institution wants you to use a cell phone authentication. I don't think those are safe. The USGovt has removed them from the allowed methods of using 2nd factor authentication for their needs.
A good password manager will change your life. You'll stop worrying about passwords and every website you log into will have a different, random, passphrase. You'll use longer passwords too, since 99% of them, you'll never actually type again. It doesn't matter if a password is 20 characters or 60 characters when a computer is going to enter it for you. For some of my logins, I also used a random username, so I couldn't tell you many brokerage login if I wanted to. I don't know it. It is random. A few times in the last 30 yrs, I've had to recite the username to someone at the brokerage company. They think I'm crazy, but are kind enough not to say it.
Also, KeePassXC uses a standardized encrypted file/DB format, so other KeePass compatible password managers can access it too. It is convenient to have that DB on multiple devices, so I never worry about losing it.
I'm not a fan of any password manager that stores passwords in the cloud, anywhere. That just seems like a terrible idea to me. Sure, the math says they are safe, but are they really? IDK.
