What is 2FA Authentication?

2FA Authentication is an extra layer of security that helps to protect your GNU STOCK account. When you have 2FA Authentication on your account some times you will be asked to enter an authentication code or OTP Code after logging in to your GNU STOCK account.

How does it work?

From time to time you log into your GNU STOCK account you will need to enter an authentication code or OTP Code. You will need to access your authentication code from a mobile app like Authy or Google Authenticator. These apps generate time-based codes that are only valid for a small period of time.

What if I lose my device?

If you lose your device you can contact our customer care to help you. Once you gain access to your account you can disable your 2FA Authentication from www.gnustock.uk/login and set it up on a new device.

Can I turn 2FA Authentication off if I change my mind?

Yes, you can manage your 2FA Authentication from https://www.gnustock.uk/workspace/settings by clicking on ‘2FA Authentication’ and disable (or enable) at any time. You can follow the steps outlined here.

What if my 2FA Authentication codes won't allow me to log in?

If the time displayed on your mobile device is incorrect for the timezone your device is set to, then your authenticator app codes may not work when you try to login. You can use this link to check if your mobile time is correct.

To synchronise the time and timezone on your device, go to the ‘Date and Time’ settings on your mobile device and reset (turn off and then on again) the automatic time setting. This should ensure the time on your mobile device is correct and allow you to log in with the authenticator app codes.

You should find that your Authenticator codes work properly after this. Syncing the time in the Google Authenticator app won't affect the time setting on your phone.
