It would be hard to meet those requirements, because the text-password system has an unsolvable trade-off relation in it.

We know "Easy-to-recall text- passwords are easy to break. Hard-to-break text-passwords are hard to recall." It would be trying to grasp the moon by our hand if we try to make easy-to-recall text-password hard to break or make hard-to-break text-passwords easy to recall.

An attempt to achieve higher security by removing secret credentials altogether would only end up ruining security. So would the attempt to displace passwords by password-dependent biometrics.

We will be able to solve this predicament only by expanding the scope of our secret credentials by incorporating Non-Text credentials on top of the conventional text passwords.

What I recommend is Expanded Password System as outlined in this 3-minute video - https://www.youtube.com/watch?v=-KEE2VdDnY0
