# Create an account & sign in

With Kalender Sync you sign in however you prefer: classically with email and password, **without a password** via one-time code — or with one click via Google or Microsoft.

## Create an account

1. Open [app.kalender-sync.de](https://app.kalender-sync.de/) and choose **"Start for free"**.
2. Enter your email address and a password (at least 10 characters) — or sign up directly **with Google/Microsoft**.
3. To confirm, you'll receive an email with a **6-digit code**. Enter the code — done.

Good to know about the code:

- It's valid for **15 minutes**; after that, simply request a new one.
- After **5 wrong attempts** it becomes invalid — a new code fixes that too.
- If you requested several, only the code from the **most recent** email counts.
- The email deliberately contains **only the code, no click link** — in many companies, security scanners open links automatically and thereby invalidate them.

## Sign in

The login page gives you three paths:

- **Email + password** — the standard way.
- **"Prefer to sign in with a code?"** — passwordless login: you receive a 6-digit code by email. Handy if you don't want to remember a password.
- **"Sign in with Google" / "Sign in with Microsoft"** — this only confirms your identity; **no calendar is connected yet** (that's a separate step with its own consent).

The paths are interchangeable: if you sign in with Google even though you registered via email (or vice versa), you end up in the same account — what matters is the **verified email address**.

**Forgot your password?** Choose **"Forgot password?"** on the login page — you reset it via email code. You can change it any time under Settings → Account → Security → **"Change password"**.

## What happens after sign-up

On first login, a short onboarding walks you through:

1. **About you** — name (optional) and consent to the Terms of Service and Privacy Policy (required). A newsletter checkbox is optional.
2. **Trial** — as a new account you get a free [7-day trial](https://docs.kalender-sync.de/en/account-billing/trial/), no credit card needed.
3. Then you continue straight to [connecting your first calendar](https://docs.kalender-sync.de/en/getting-started/connect-first-calendar/).
