How it helps carers

Margaret can't read her emails. Her son shouldn't see her passwords.

Margaret is 82. Her eyesight has faded, and the little codes her bank sends to her phone are impossible to read. Every week she calls her son David: "Can you help me get into my account?"

For years the only answer was to hand David every password. He didn't want them. If anything went wrong, he'd be the one holding the keys — and Margaret lost a little more of her independence each time.

With Secret Digits

Margaret saves her logins in her own private vault. She chooses David as her helper for just the accounts she needs help with. David gets a "Sign in" button — the password stays hidden from him.

When the bank sends a sign-in code to Margaret's phone, it can be forwarded safely to David, so he can finish signing in without asking her to read anything.

Margaret stays in charge. She can stop David's access at any time, and see every time it was used. Even Secret Digits can't read her passwords.
