Immediately see how many characters are allowed for a password.

Are you using password managing tools, such as KeePass, 1Password or LastPass? Ever had the problem to find out the maximum allowed length of a password when you were registering for a website and wanted to generate a password with your managing tool?

Password Length Inspector will help you identifying the constraints of ANY password field on any website. After installing this extension, you will find a small indicator next to every password field, telling you how many characters may be entered into that specific field. In case there is no character limit, infinity will be displayed. This way, you will have never to figure manually (for instance by digging in the source code of the website) how many characters are allowed to be entered in a password field.

One Note: in case there is no limit set on a password field, this does not automatically mean that the website will accept passwords with any length. Instead, it can happen that after submitting the form containing the password field, you'll get a validation error, telling you no more than XYZ characters are allowed. Unfortunately, this information may not be visible or detectable before actually submitting a form.

Works on quite a few sites but uses an infinity sign when it doesn't know. There should be a way to crowd source info from users to make a larger database.

Very helpful. Of course, doesn't help in the case of server limits, but at least if available on client side you know.
