Authentication

The Sign-in Methods section in your Account Settings lets you manage how you sign in to Treasury. Treasury is passwordless — you sign in with a passkey, a connected account, or a code we email you, never a password to remember or leak.

You can use any combination of the following secure sign-in methods — Passkey, Google, and Apple:
Passkeys let you sign in without using a password.They’re a modern, secure login method that uses your device — such as Face ID, Touch ID, or your computer’s built-in authentication system.

​
Add a Passkey

  1. Click Add Passkey under the Authentication section.
  2. Follow your device’s prompt to create a passkey.
  3. Once created, it will appear in your authentication list (for example, “Mac (Chrome)”).
You can have multiple passkeys (for different devices) or remove one at any time by clicking the × icon next to it.
Removing a passkey means you won’t be able to use that specific device to sign in until a new passkey is created.

​
Sign in with an email code

Every account can also sign in with a one-time code sent to its email address. You don’t need to set anything up.
  1. On the sign-in page, choose Email me a sign-in code.
  2. Enter your email and choose Email me a code.
  3. Enter the 6-digit code from the email, or tap the link in it. Both expire in 5 minutes and work once.
If you change your email address, codes and links sent to the old address stop working.

​
Skip passkey setup

If creating a passkey fails when you sign up, choose Skip for now on the passkey step. In browsers that can’t create passkeys at all, such as the Instagram or TikTok in-app browser, Treasury skips this step for you. From then on, sign in with Email me a sign-in code. A passkey is optional: add one anytime from this page.

​
Using Multiple Sign-In Methods

You can enable both Passkey and Google Authentication for added security and flexibility. For example, use a passkey for quick sign-ins on your personal device and Google sign-in when accessing Treasury from another location. Your authentication list displays the methods currently linked to your account, including when each one was last used.
It’s a good idea to keep at least two authentication methods connected — for example, Passkey and Google — so you can always access your account, even if one method becomes unavailable.
