Big news today folks. Today we're launching Login with Teller, the safest way for users to connect their bank accounts with the financial apps and services you've been building during our developer beta.
Also, today we're happy to announce that we're making our APIs completely free of charge*.
Going from the first time opening a Teller powered app to actually using the app with live data from your accounts takes less than 25 seconds.
Login with Teller makes some essential and fundamental improvements to how users give consent to financial apps requesting access to their bank accounts. Teller places user needs first, making it an easier decision for users to trust your app.
-
Safer and easier for users to trust. Instead of your app collecting user credentials, users enroll their bank accounts directly with Teller. You no longer have to worry if your apps are keeping user authentication data safe, and users no longer need to worry that your apps are able to. Teller gives your app a token representing the user that's useless to anything other than your app. Safeguarding users and hiding complexity from application developers is our job and we're happy to do it.
-
Streamlined onboarding. When a user shows up who has connected their bank account before by using another Teller powered app there is no need to have them do that again, so we don't. We get the user's consent and send them back to your app. Users can start using your app in seconds instead of double-digit minutes.
-
Giving users control. Your apps declare the access requested up front. Users can opt-out of anything your app requests and it should handle those cases gracefully. Apps can request additional permissions from the user at any time. We encourage you to request the minimum access necessary, demonstrate value, progressively build trust, and gradually request further permissions from the user as and when needed.

Users can choose to hide entire accounts from an app before authorizing.
Login with Teller uses TAuth, today we're open-sourcing tauth_proxy
to help you develop more secure financial apps.
That's all for now folks. Create an application, have a read of the TAuth docs, and let us know what you build. 😊
