@karakayasemi Is this the correct method or is there any better way? Or, try it twice?

@skshetry as far as I understand, your concern is the key change can cause unwanted fails.
Luckily, we are accepting before and after 3 timeshifts when validating secret as you can see in here https://github.com/owncloud/twofactor_totp/blob/master/lib/Service/Totp.php#L120.
This means every generated key is valid for minimum 90 seconds and maximum 120 seconds. So, the key change should not be a problem.
