Yep! Use the Sync feature to keep your progress and current tasks the same across all your devices. Sync uses a simple email / password login - social sign in is not available for privacy reasons. Please bear in mind that you cannot disable syncing once you have enabled it, without deleting your account.
To enable Sync, head over to your profile (button in top right), then go to the settings (little gear / cog icon in top right), and click the toggle for 'Sync'. Enter an email and password you'd like to use.
Then, on other devices, you can either sign right in using the 'I already have an account' option when you first install the app, or you can head to your profile, then settings, and hit 'delete account' - reopen the app and follow the 'I already have an account' button to sign in.
