Google's penchant for denying access to your Google account
Uh, so someone else has had:
"Sign-in attempt was blocked. Someone just used your password to try to sign in to your account. Google blocked them, but you should check what happened."
I thought it was just me (not). Every time my phone (running K9 mail) connects to a wifi hotspot; thunderbird similarly. Makes me want to dump google email; I keep putting it off, but I have no strong attachments to my google email addresses. Must soon realise this laziness costs me more effort.
