It is normal to have automatic logoff from time to time, especially in email accounts. But the reports point out that the problem has happened with various services and platforms: Gmail, YouTube, Maps, Chrome, Chromecast, Android, among others. Even, the corporate accounts were also affected. What most caused concern was a warning that the disconnection occurred because of a change in the account, which made many people think of an invasion. But on Twitter, the tech giant Google said there were no security issues with the accounts.
— Google (@Google) February 24, 2017 Some have associated disconnection with the serious flaw that hit Cloudflare, but, at least so far, there is nothing to prove the relationship between the two issues. Everything indicates that it was just a coincidence: the two cases were in evidence at almost the same time. If Google has already discovered the issue, simply it will choose not to reveal. In the help pages, the company says it is investigating the problem but points out that there is no indication that the cause occurs due to any security failure or flaw. Apparently, it was just a bug. Just sign in again, and everything will be resolved. In the same warning, the company warns that users who use 2-step verification may have delays in receiving SMS with the activation code. If this thing happened with you, then the company suggests using the backup codes option.
