How can such a simple idea provide strong security?

Often the best ideas are the simplest!  The technology has been tested by several ethical hackers and they have failed to crack the TentoiDs.  But there is no such thing as 100% security and we are constantly researching ways of improving the resilience of our tokens to attack.

What if I lose my phone?

The TentoiD is a personal security token that could give access to bank accounts as well as to secure payments for online purchases.  So it should be treated with as much care as a wallet full of cash and credit cards.  All smartphones should be protected by one of the many disabling apps that are widely available – the phone manufacturer usually supplies one. It should also be locked using a biometric (fingerprint, face or voice recognition) or a strong password.

If the phone is lost or stolen, the user should revoke their TentoiD and request a new one.

What if I haven’t lost my phone – just left it at home/work? How do I log in to the company network or a website?

You can replicate your TentoiD across several devices – so you could have a copy in your home and work PCs as well as in your phone.  That way, you will always be able to get authenticated, even if you have mislaid your phone.

What happens if I change my phone?

First of all, it’s a good idea to cancel the TentoiD in your old phone.  The TentoID is valuable and you wouldn’t want anyone else trying to use it. You can do this easily within the TentoiD app.  When you do, you will get an email from the website where you originally registered, asking if you wish to download a new TentoID.  You can do so once you have installed the TentoiD app in your new phone.
