What are the unlisted password requirements?

Since I created my NextDNS account, I used a password manager to generate the password. The website accepted a password that was over 30 characters long.

When I went back to log in, I kept getting an “incorrect password” message. After resetting it several times, I’m beginning to wonder if the system accepted my password during account creation but silently truncated it to some undocumented maximum length instead of displaying an error.

I’ve shortened the password to 22 characters, and I still can’t find any documentation stating what the maximum password length is for NextDNS. Does anyone know?

Neither Google nor ChatGPT has been able to find the answer in NextDNS’s wonderfully documented information.
