Implement login

[gjermundgaraba]

Implement login using Web3Auth.

• When the app opens, check if the user is logged in

  • If yes: go to the main screen
  • If no: open the login screen stuff

• Make sure the logged in user credentials are persisted between app-opens (You need this also for the check from the previous step)

  • This might be built-in with Web3Auth 🤞

• It should be possible to log in with:

• [x] Email (Passwordless)

• [x] Social (Google, Facebook, Twitter, Discord)

• [ ] Seed phrase (Create and import)

Almost all here is done except the seed phrase.
