Wickr Me uses an anonymous username while Wickr Pro uses an email address as your username. This allows for password resets and verification of ownership.
Wickr Me accounts belong to whoever has the correct credentials to log in to a Wickr Me account. No ownership can be verified because we do not keep personal information for any portion of Wickr Me. If a user links a phone number or email address in Wickr Me we cannot decrypt that information and view it.
Wickr Pro has the following additional features:
- Conference/group calling
- Administrator controls for the network (Network-wide security settings, i.e., forcing all users on your team to keep "Require Authentication" turned on)
- Ability to create Rooms with moderators
- Larger rooms
- Larger file sizes
- Longer ephemerality (Expiration timers)
