Gah what then? I use strong passwords but almost all of them flow through my clipboard.

I used to use Keepass with auto-type. I had a hotkey for it, and it would recognize the site based on the browser window title.

That would probably be the best of both, no clipboard, and no browser addons.

Instead of checking the TLS certificate or the domain, you are depending on fak3b00k.com not implementing the same title tag as Facebook?

That's something to think about. But I'm not sure how I would end up on fak3b00k.com unless something changed my bookmark for it, or I really mistyped it but if I did that the URL being different is a dead giveaway.

Some password managers will type the username/password into the browser (through a virtual keyboard I think), not copy-paste them to protect against clipboard attacks. Eg. Keepasssc

There are non-browser-extension password managers that still emulate you typing on your keyboard, rather than going through clipboard.

Personally I use rofi-pass to access GNU pass passwords (so just a hotkey and search for password name)

I'd warmly recommend it (or whatever other client you use for GNU pass) but I'm sure you can find similar functionality for any other decent password manager.

Firefox extension, Passhash NG.

Makes them easy to use, with no saved PW.

I a simple algorithm to generate a password based on the name of the service you are using, interleaved with a constant master password you remember. You can do the same thing with a password-manager password + clipboard, interleaved with a constant master password you remember, which should be even better.

Mine clears the clipboard after 10 seconds.

You do realize that in 10 seconds your computer can achieve a lot of stuffs right?

I don't think a webpage can read clipboard without the user manually pasting.

If there's some malicious desktop program running on your machine at the same time as the password manager then you're probably screwed regardless of whether the password passes through the clipboard - but maybe there's some subtleties I'm missing here.

I've accidentally pasted sensitive passwords enough times that I know the procedure is prone to errors.

If I have to do it, I immediately copy something else right afterwards, to avoid an accidental paste later on.

10 seconds auto-clear (which is configurable) is short enough to prevent me accidentally pasting onto some other site.

Could be better if it auto-cleared after a paste, but not sure how feasible that would be.

For example it could just read all the passwords from the password manager's UI.

Between Keepass, 1passwword, and lastpass I've never seen a password manager that just shows the password without the user explicitly choosing to reveal it

1password has the option to do so and I do it on my home desktop computer. Obviously on mobile devices it would be a bad idea and on those I leave that option in it's default, disabled state :)

The purpose of clearing clipboard is so you don't accidentally paste it into a chat window or something. Not to protect against malicious programs.
