Kindly I ask your attention.
RiennaCruzar has a good answer, all you have to do is click once to send it for a check.
I don't know if that's what you seek, but there will be a lot of add-ons that could login automatically just by a click or keystrook.
Start your browser, search with different search engines and use different phrases:
Firefox Auto Login plugin:
https://www.google.nl/#q=Firefox+Auto+Login+plugin
Here you can find a lot of linsk to go for, like:
https://addons.mozilla.org/en-US/firefox/addon/secure-login/
When the add-on isn't compatible with your browser, you could try to find it with Firefox.
Left on top, click Firefox. Go to Add-on and click on it. Now choose Extentions, at the right top of the list you will find a search bar. Copy/type here the name of the program and see what the result wil be.
Hopefully I let you known enough, that you will find the answers you seek!
Good luck and have fun doing it!
Best Regards,
