Can I use Magic with JWT?
Yes! You can simply use Magic for authentication, and your own JWT implementation for authorization.
Here's high-level how JWT would work with Magic:
User logs in with Magic, you're returned the DID token
Validate the DID token in your backend with our admin-sdk magic.token.validate(did) method
Call our admin-sdk method magic.user. getMetadataByToken(did) to grab the user's unique ID and email address
Store that data inside a JWT token and then move forward with your JWT implementation
On subsequent requests to your server, just verify the JWT
For example:
The client-side magic.user.getMetadata() while I'm logged in returns:
Wrapped in a JWT, that is:
Just enter that JWT on https://jwt.io to see it decoded back into the metadata object.
