How to regain Gmail account that is been temporary locked out
Gmail account is has got an error of temporary locked out during busy work. Google will automatically lock account if they found any abnormal activity for sake of security and hacking. Time span for lock is mostly few minutes to 24 hours maximum.
Before that you must know why it had been locked out, so that you may take care to avoiding lockout again.
Reasons behind locked out
Receiving, deleting, or downloading large amounts of mail via POP or IMAP in a short period of time.
Sending a large number of messages to many people at one time.
Being logged into or synchronizing Gmail emails on many computers, clients, or mobile devices simultaneously.
It might be also because of browser-related issues. If it found your browser continually reloading while attempting to access your Inbox, it’s probably a browser issue, and it may be necessary to clear your browser’s cache and cookies.
Providing access to file-sharing, file-storage software, email, Analytics services, browser extensions, or third party software that automatically login to your Google account and perform the suspicious activity.
How to unlock Gmail account quickly?
There is only one way to unlock it, by waiting for a while at-least an hour or something. I personally got my Gmail account unlocked in an hour. But it is said by Google support team that it might take 24 hours to unlock your account.
You can still try these options to regain as soon as possible:
Remove POP and IMAP settings from any email client software.
Close multiple instances of browsers with Gmail login.
Revoke access to all third-party apps and software.
Clear cache of browser and reopen.
Meanwhile, if you are using any Chrome or Firefox extension that has access Google Account, they must be disabled temporary until your account is re-activated. If you are again locked out after enabling extension, then you must permanently remove that extension as it might be the culprit. There are also few instances when you message blocked to Gmail ID.
