I once spent 15 minutes trying to register in a local Domino's website which kept bugging me about lack of a special character - even though I had one in it. Turned out to be that the app truncates the entered password after the first 20 characters and only considers the first part. Thankfully the special character was after the 20th position so I noticed the error and fixed it, but if it wasn't I'd be wondering the next time I'm logging in why it's not letting me login with a valid password.

Why do you need a secure account to order pizza?

How else are they going to run pepperoni-based big data analytics?

I've had the same problem with Verizon, in the past the password would only store the first 20 characters. Took me an hour or two to figure it out and fix the problem. I'm not sure if that's still the case, hopefully not.

My issue with Verizon is they lock an account after 3 bad attempts, and the "username" is the cell phone number for the account. Which seems to be slurped into some automated brute force engine.

Every single time I want to login, I have to do a password reset first. Makes me which I had the phone number to every manager in the company, so I could lock them all out every day.

Also, since having the phone is the only second factor for authentication, that's all you need to access an account.

You might not even have noticed if the login form truncated the input as well before hashing it. (You probably would have noticed after some update to their website removes the truncation though.)

Presumably it also truncates the password when doing sign-in?

I've had that with work passwords - using my password generator I give them a 64-character gibberish mess, but it turns out that they only accept 16 characters, and I rendered my account useless until they could reset it for me. How frustrating.

Hm, yes. I had that happen with a '#'. Presumably there was some nasty evaluation going on and the rest of the password was treated as a comment.

I wonder why I never pursued that.
