It’s 2023, why are websites actively preventing pasting into fields like passwords and credit card number boxes? I use a password manager for security, it’s recommended by my employer to use one, and it even avoids human error like accidentally fat-fingering keys, and best of all with the credit card number I don’t have to memorize anything or know a single digit/character!

I have to use the Don’t Fuck With Paste addon just to be able to paste my secrets into certain monthly billing websites; why is my electric provider and one of my banks so asinine that pasting cannot be allowed? I can only imagine downsides and zero upsides to this toxic dark-pattern behavior.

There is even a mention about this in NIST SP 800-63B, a standard for identity management that some companies must follow in the USA, which mentions forcefully rotating passwords and denying “password paste-in” as antiquated/bad advice:

Verifiers SHOULD permit claimants to use “paste” functionality when entering a memorized secret. This facilitates the use of password managers, which are widely used and in many cases increase the likelihood that users will choose stronger memorized secrets

Edit: I discovered that for Firefox users there’s a simpler way than exposing your secrets to someone’s third-party addon. Simply open about:config, search for dom.event.clipboardevents.enabled, and change it from true to false.

Edit 2: As some have pointed out, that config value interferes with regular functionality on some sites. Probably best to leave it alone unless you know what you’re doing.

        Good idea, although this wouldn’t tell you if they truncated the password at 9 characters instead (or 10 or 11 characters etc).

        So you would have to try different attempts without making too many in one sitting that gets you locked out.

        If you tried your password without the last character, then I think that would tell you if ANY truncation is being used (but it won’t tell you whether it happened at the 8th, 9th, 10th etc character). But that seems like the best thing to try first just to rule it out.

        I checked network logs. Apparently my bank encrypts both uid and password before sending. I put 8 chars and it gave error so I’m assuming no
