XF 1.5 2 Step Login - Reset Phone


Active member
Hi Guys,

Trying to login to my test site to get the ball rolling on our move, and I've had a new phone since then which doesn't have the site on it. How do I login?

It says I can use a backup code, but I don't have this either.

The back up codes exist for this reason - you should ensure you download a copy of them.

In the meantime, add this to the library/config.php file:
$config['enableTfa'] = false;

That will enable you to log in and disable TFA.

Ensure you remove that line once you have done so.

For 2FA I'd suggest that you use Authy. It works across multiple devices and unlike Google Authenticator it allows you to make a backup so that when you change phones you can restore all of your accounts used with Authy.

but if server faster or late then google time none of those not works
Which is why it's important to make sure your server time is correct.

Oh and your point isn't relevant to this discussion which is about resetting logins when you don't have the original phone you used for authentication.

DST doesn't affect the underlying time in GMT/UTC. It just adjust the relative time around that. So no DST issues (as long as it's done properly -- it should generally happen automatically based on the selected server time zone).
