David uses a bunch of different browsers and everyone wants to save his passwords. It seems easier, but he says that it fills in the wrong password often. Leo says that's probably because David has multiple password managers and they are fighting. It's like antivirus software. It's best to have just one. Relying on the browser saving passwords isn't safe because that's not their main business and many have security flaws. David should use one password manager like LastPass, and it will input the right password.
