I have a gmail account and a google account. I also have old reliable Nexus 7-13 pad and a LG mobile phone. Lately, when i try to read my emails from Thunderbird and click on the gmail account, I get confronted by Google by asking me to verify it. sometimes, unknownst to me, the password i enter is wrong, so i have to go through the verification code mode. Once that is accepted, than i am able to read my gmail in TB and etc. Now, this is on my desktop. A few days later I may use my pad or my phone and again i am being asked by Google for my password in order to use my phone. I enter the same password that gets me through on my pc,but here it comes back as incorrect. So my question is why won't it accept the password that was verified on my pc and not on my phone, or pad? Does Sync have anything to do with this? I do not have sync setup at all...never had.
