Bookmarklet for quick login

fill-login.js

javascript:(function(){var d=document;s=d.querySelector;s.call(d,'input[name*=email]').value='YOUREMAIL@company.com'; s.call(d,'input[name*=pass]').value='SECRETPASSWORDHERE';s.call(d,'button[id*=login],input[type=button][id*=login],.btn-login').click(); }())

This is a bookmarklet. To use it, add a bookmark in your browser and use the above text as the URL.
This bookmarklet will fill email+password login forms and submit them. You'll have to update it with the desired email and password and it's obviously not a good idea to use it with real-world credentials. Use it just for testing, with test accounts.
It won't work for every imaginable login form since it was mainly created for the projects I work on, which are consistent about the form field names.

This is great!
Another way to do this would be to create a function 'doit()' in a general js import and call this from the bookmark like:
<a href="javascript:doit();">doit</a>
