Evaluate auth and single sign-on (SSO) solutions for your apps

Hi Guys - As a user, we all know the complexity of the passwords with first creating and remembering them. But as a developer making sure we are using strong salt and hashes with strong key rotation and then storing and processing hashed password on servers. It consumes so much processing and use quite a bit computing resources.

We are building a simplified auth solution that would remove the passwords and simplify user experience.

So I would like to understand from the developer point of view:

• How to evaluate auth/SSO solution for your apps?
• Would you prefer to use password-less or still use username/password?
• What solutions you are using currently for auth?

Thanks for your support!
