ZyXEL VMG 1312-B10A: setting passwords in the web GUI
« on: June 06, 2018, 01:10:50 PM »

I have had stupid error message "requires 6 letters and at least 1 digit" or the like when setting the password. I got this when I set the password to password, so understandable enough. But I also got the same error message when I tried to set a complex strong password which had letters digits and punctuation in it, all ascii, no whitespace.

Has anyone else had this? Is it just a bug? Is it objecting to some of the characters?

The really weird thing is, that same strong password was working and is working on the other modems, so how did I set it? I am trying to remember, maybe I got round the issue before by putting the right config into the config file directly. I was trying to set it back to password for the benefit of kitizen michty_me in the config file I posted for him in another thread.

You can indeed change the password by loading up a saved config file, that is how I worked around the problem and got it back to the strong password that I wanted.

Question: the password is encrypted in the config file. I don’t suppose you can just put in the password that you want straight, can you?

(Would only make sense if it is a system that detects plain versus encrypted passwords because the entry is marked in some way with something distinctive surely?)

You can edit the config file, there's a good chance it'll work [and re-encrypted maybe?] but through the GUI I set the supervisor password on mine to 1234 so idk.

Edit: Maybe it wants at least 1 digit. Also try a password length of 20 and see if it has a character limit and which is the limit.

Edit2: The reason I'm optimistic about editing it to plain text in the config is that after a firmware upgrade from an older un-encrypting version, the password of older configuration files is preserved but encrypted.
