Hi! encforever No worries, please do be sure to ask your friend to contact us and we can help them further. The password is not in relation to the Enjin Platform (cloud.enjin.io), this is a unique password for you to access your wallet using the Enjin Wallet app.
If they still has the recovery phrase of their wallet, he can reinstall the app and set a new password up from there. Albeit, please don't recommend this if they do not have their recovery phrase(s) of their wallets as they will end up losing access to their funds!
You can check here more on how to do this: https://support.enjin.io/help/i-forgot-my-password
Let us know if that helps, but do ask them to contact our support team where myself and rest of us can help them further. 😀
