# Logging in

> Sign in to Odin with email OTP or passkeys

Odin uses passwordless authentication. Enter your email to sign in: if you have a passkey registered, Odin asks for it first; otherwise it emails you a one-time code.

## Sign in with email

<Steps>
  <Step title="Enter your email">
    Go to [odin.borghq.io](https://odin.borghq.io), enter the email address associated with your account, and click **Continue**.
  </Step>

  <Step title="Check your inbox">
    You'll receive an email from Odin containing a six-digit verification code. The code expires after a few minutes.
  </Step>

  <Step title="Enter the code">
    Type the six-digit code into the verification screen. You'll be signed in immediately.
  </Step>
</Steps>

<Tip>
  If you don't see the email, check your spam folder.

## Sign in with a passkey

If you've registered a passkey (fingerprint, Face ID, or a hardware security key), Odin uses it automatically, so there's no separate button to click.

When you enter your email and click **Continue**, Odin checks for a passkey before it sends a code. If it finds one, your device prompts you to authenticate and the button reads **Waiting for passkey**. Confirm the prompt and you're signed in, without an email or code.

If you cancel the prompt, have no passkey on that device, or your browser doesn't support passkeys, Odin emails you a six-digit code instead.

<Tip>
  On supported browsers, your saved passkey can also appear as an autofill suggestion on the email field, so you can sign in before clicking **Continue**.
</Tip>

Passkeys are the fastest and most secure way to sign in. See [Profile & Security](/platform/profile) to set one up.

## Sign in with Google

Instead of entering your email, you can click **Sign in with Google** on the login page and choose your Google account. Odin signs you in directly, without an email or code.

This only works if your Google account uses the same email address as your Odin account. The same access rules apply as with email sign-in: if that email doesn't already have access, you're redirected to request one.

## First time signing in

Odin is invitation-based. To access the platform, you need to be invited by an existing member, or your organisation must have **domain join** enabled (which lets anyone with a matching email domain join automatically).

If you don't have access yet, the login page will show a **Request Demo** option where you can submit your details and our team will get in touch.

## Switching organisations

If you belong to multiple organisations, switch between them using the organisation selector in the sidebar. Your session persists across switches, so you do not need to sign in again.
