Integrating firebase auth with my Glide Apps

Hey_How can we use Firebase Auth to let user login to our glide app ?
Another question is how can we let external users singin to our glide app and how can write the user related changes e.g. password changes, back and forth ? How would the same work for remembering users on devices and passwordless logins ?

Your only secure options are to use the authentication options that glide already provides. Trying to build your own will not allow for the ability to properly secure user data.
