I always know my email password just in case I'm in a situation where i either don't have my password manager or something happens with it. Your email is the account that ties everything together so I think everybody should always know it just as a occasion.why two? I know only one password, that of my password manager. The passwords for my email accounts are saved in there too. I take extra precaution and regenerate maximum security passwords for my emails every year or so, just in case. Also have 2FA enabled.Have an extremely secure email and password manager password that can be remembered, everything else can be extremely complicated and not easy to remember. It's a lot easier to make and remember 2 really good passwords, where as people without password managers reuse passwords, even on sketchy sites, and with the 20 passwords they need to remember they opt for weaker passwords so they can actually remember them.Of course, none of this matters if you're just going to link everything to an email account, which provides a single point of failure for every account, or dox yourself by sharing your real-life data like your phone in the Interwebs, at which point your entire security is completely void.I think most sites have a cooldown on logins. So you can't just keep spamming a gazillion password combinations or your IP will get locked out. The benefit is to quickly have a secure and unique password if you want to sign up for a site, and have them all easily accessible in a browser extension (or desktop client). The key here is unique, because if one site gets compromised, your other accounts will stay secure, and that's the biggest security concern, because most people I would guess just use the same password everywhere.
It happens quite often, depending on how shady the sites are that you sign up on, that their database gets compromised, this is a website that can show you if that happened to your data:
