"Google Account: sign-in attempt blocked"

[Yakibomb]

Since updating to 10.10.3 I've been getting email notifications from google saying "We recently blocked a sign-in attempt to your Google Account...." every time I reboot my mac, or wake up it after a few hours. I've tried changing the settings to allow for 'less secure' apps but I still get the emails 😕

Anyone else experiencing this?
Any suggestions 😕

You are signed into Google in done System Preferences pane. So when you restart, hence logging out of Google and when restarting immeadiatly re-sign back into Google. Now Google servers are angry for this log out log log in.

You aren't alone; since upgrading I've gotten 20 of those emails. I anticipate them when checking my email every day. It's annoying.
