GMail POP password problems
GMail started rejecting my password when I accessed it through POP from Mail.app. This isn’t the first time, and since I remember how difficult it was to find the solution the first time, I thought I’d document the solution in a blog post for all eternity.
Certain activities will trigger the “you may not be human” alert at Google, causing them to lock your account for non-web access. Very annoying especially since non-web access doesn’t give you any user-friendly error message, and since your account continues to work through the web, you basically suspect your mail application is at fault.
The solution is to go to Google’s UnlockCaptcha page and do the captcha test there. I found this solution on Andrew Escobar’s site.
