OnesID is the digital identity in your pocket with which you can access a growing number of services securely and without remembering a password.
Your phone securely stores your account's private key, with which you can authenticate yourself against all supported applications.
Once you activate your digital identity, your phone quite literally becomes the key to your digital world but unlike the key to use to open your house door, this one is virtually impossible to duplicate.
