Hi there, not sure if this is happening to any of you.
I constantly check my Adsense daily earnings, by cellphone (Java Opera mini), by Tablet (Android Opera Mini) and Desktop (Firefox, Opera). But this week when on my tablet I was asked to enter a captcha for security reasons, then on my desktop I was asked to confirm my previously confirmed cellphone and to enter a confirmation code.
Really odd because I don't check as often as 3 months ago (I used to do it daily at least 2 times per day and one at night). I'm still wondering why Google won't release an official app (I don't feel like entering my credentials on third party android apps)
*In case somebody didn't know Opera Mini uses a sort of proxy servers so it appears as if you were checking from another country, still this never meant a problem in the past.
