# Use Latch in your browser

No installs needed. You need a Level Up account and a password manager (1Password, Apple Passwords, Bitwarden...).

## 1. Sign in

Open https://latch.leveluptoday.ai and click **Sign in with Level Up**.

## 2. Create your key (once)

Your key is two parts: a **public key** (`age1...`, safe to share) and a **secret key** (`AGE-SECRET-KEY-1...`,
yours alone). Latch never stores the secret key. If you lose it, you lose access until you make a new one.

1. Open **Identities**, then **Register your key**.
2. For **id**, enter something like `yourname-laptop`. For **display name**, enter your name.
3. Click **Generate a new keypair in this browser**.
4. **Save the secret key now** in your password manager, as a new secure note named "Latch key". It is shown once.
5. Click **Register**.

Your key now waits for an **admin's approval**. Rob will confirm with you directly, then approve it. Until then it
can't open anything. That is on purpose: nobody can quietly swap your key for theirs.

## 3. Get access to a file

Ask an admin for access ("please give me `homeonmaui/mls.yaml`"). Once granted and approved, it shows up under
**Files**. You only ever see the files you have access to.

## 4. Open a secret

1. Click **unlock** at the top right and paste your secret key (`AGE-SECRET-KEY-1...`).
   It stays in this browser tab only and is forgotten when you close the tab.
2. Open the file under **Files**. The values are decrypted in your browser.
3. To change a value: **Edit**, then **Save (encrypt & commit)**.

## Lost your secret key, or a new computer?

Register a new key (step 2) and tell an admin, who approves it after checking with you. Then remove the old one on
**Identities** if you no longer use it.

## Tips

- Never paste secrets into chat, email or documents. Share access to the Latch file instead.
- Leaving a shared computer: close the tab (that forgets the key) and sign out.
