As an advice, you can ask people to add another key to their account and allow login with a passphrase and from that passphrase derive the private key (they added to their account).
The scheme that makes most sense and is used by Steemit.com looks like this

        SHA256(accountname + role + password)

where role is owner, active, or memo. The has is used as the private key. Python code looks like this:

you can try the web wallet from https://btsbots.com
or try android app from google play:  https://play.google.com/store/apps/details?id=com.idnt4zyo1d95xegwtxmk0
