Tunnelblick - Password or authentication failure

    Tunnelblick stores usernames and passwords in the macOS keychain. If you are having authentication failures then you should first delete the keychain entries:

    1. Open keychain access utility by navigating to your Applications folder and then Utilities.
    2. Select Login under keychains and all elements under Category.
    3. In the search box in the top right, enter Tunnelblick to filter all the Tunnelblick keychain entries.
    4. Select all the Tunnelblick entries, select edit | delete.
    5. Close Tunnelblick and open it again and try to connect.

    If you continue to have authentication issues please see I receive an ‘authentication failure’ message. What can I do?
