Gmail Security Denying UVM

[Camoron]

How do I get around this? I try using the really long URL in the WEBALERT part of the following log, but Gmail tells me they're  preventing my sign in attempt as they think I've stolen the password. I've already gone to the other URL and enabled device access, but Gmail's security still blocks me out. Is there anyway I can loosen these security settings? This is such a PITA. Using Enhanced Integration with Gateway setup as smtp.gmail.com on port 587, and individual users set up with imap.gmail.com as their Email Server.

Check out this log:

I think I figured this out. Just want to bump the thread with my solution in case others need help:


Go into individual users' account settings and go to Sign-in and security, then change Allow less secure apps to ON. Voicemails all just came through after doing that. Now I just have to do it for a ton of other email addresses...
