[Proposed Feature] Support Social Sign On (SSO)

[alukach]

Description of Feature:

Rather than creating unique credentials for Source Cooperative, users should be able to alternatively utilize existing authentication providers if they so choose (e.g. login via Github or Google).

Ory supports many providers already (link):

We would want to select which providers we would like to utilize (I would suggest Github, Google, Microsoft).

What value is this feature adding to Source Cooperative?

Make it simpler to login with Source Cooperative, no need to remember/store additional credentials.

Note

We should ensure that there's a reasonable path forward for existing users that would like to utilize SSO. I worry that Ory would attempt to create a new user rather than correlating the SSO identity with an existing user.
