New Amcrest IP5M-T1179EW
Windows 11
I changed the admin password after setting up the camera. I am currently logged into the camera now and it is functioning properly.
However, the incredibly frustrating IP ConfigTool reports "Incorrect username or password" when I try to login with it. The Settings are correct, yet, when I attempt to login it fails.
This is happening _while_ I am logged into the camera using Amcrest View.
ConfigTool accepts neither the new password or the default. The only way to get it to login is after I press the physical reset button and use the default login/password.
What am I doing wrong here?
IP ConfigTool Won't Login
Re: IP ConfigTool Won't Login
I don't think you're doing anything wrong. I suspect an incompatible change to Windows.
I last used IP Config about three weeks ago. I could log in only if I typed the password. The login would fail if I pasted the password from my password manager. Now, login fails even when I type the password. In addition, the tool crashes when I try to set the default password using the "Login" button.
I haven't tried factory reset.
I'm running Windows 10 Pro Version 22H2. I'm wondering if one of the following quality updates (and perhaps an analogous one for you) has finally knocked over IP Config:

@check6, thanks for the reply. The frustration had risen pretty high trying to get ConfigTool to function. At least I know I'm not losing my marbles!

You are welcome.
Re: IP ConfigTool Won't Login
I misspoke: IP Config crashes when I try to set the default password using the "Settings" button. Whether or not it crashes seems to depend upon length.
The default I want to set is 20 characters long. When I paste it into the "Default Password" field of the "Settings" dialog, there's no way to see the characters. Only 16 dots show in the "Default Password" field. If I press "OK", IP Config crashes. If I delete the last dot and press "OK", IP Config does not crash. The number of dots in the "Password" field I see by pressing the "Login" button grows from 5 to 15.
In any event, I am not able to use IP Config to log into cameras using passwords acceptable to the web UI, when I last did so around the first week of April.
