Wickr does not keep usernames nor any passwords on our servers, and as such cannot reset a password if you've lost it.
If your password is not accepted, your best bet is to try logging in using Wickr Me on multiple devices like Windows, macOS, Android, etc. You have up to five attempts on an individual device before it's suspended for 24 hours, so please be careful to not lock yourself out! This is by design to ensure all of our users are as private and anonymous as possible.
If your password is still not accepted after trying on multiple devices, you'll need to create a new account to continue using Wickr Me. To create a new account: Create-and-Register-a-Wickr-ID
If you forgot your username, your best bet is to ask a friend you have contacted outside of Wickr (email, phone, etc.) to remind you of your username as it will be in their Wickr Contact list.
