PreVeil's end-to-end encryption uses Private encryption keys

Your Private Key

Your private key is a very big number—about 77 digits long—that is is virtually impossible to guess and is created when you set up your PreVeil account. There’s one private key for each email account you set up in the PreVeil system. If you’ve set up two email addresses (for example for personal and work emails) then you will have two private keys.

What Your Key Does

Your private key is very important because it enables access to all of your encrypted information. Without it, you can’t read or send emails. The PreVeil system doesn’t use passwords; your private key is what authorizes access to your information.

Where Your Key is Kept

A copy of your private key is stored on each computer or phone that you’ve authorized for PreVeil. No copy of this key exists anywhere else, not even at PreVeil.

Using PreVeil on Multiple Devices

Each phone or computer must contain your private key in order to use PreVeil. You can add your key to a new device after installing PreVeil. To do so, you must have access to a phone or computer that already has your private key installed. During installation on the new device, you’ll be guided through the process of “transferring your account” (i.e. transferring a copy of your private key) from the old device.

PreVeil's Approval Group technology can be used to reconstitute private keys.

Your Recovery Group

A recovery group is a set of PreVeil users who can help you recover your private key in the event that you’ve lost all your phones and computers that have PreVeil installed on them (i.e. you’ve lost all copies of your private key).
