+## Reset Admin Password
+
+If you've forgotten your admin password, you can reset it by following these steps:
+
+### Reset Admin Password in Docker
+
+To reset the admin password for Open WebUI in a Docker deployment, generate a bcrypt hash of your new password and run a Docker command to update the database. Replace `your-new-password` with the desired password and execute:
+
+1. **Generate bcrypt hash** (local machine):
+   ```bash
+   htpasswd -bnBC 10 "" your-new-password | tr -d ':\n'
+   ```
+
+2. **Update password in Docker** (replace `HASH` and `admin@example.com`):
+   ```bash
+   docker run --rm -v open-webui:/data alpine/socat EXEC:"bash -c 'apk add sqlite && echo UPDATE auth SET password='\''HASH'\'' WHERE email='\''admin@example.com'\''; | sqlite3 /data/ollama.db'", STDIO
+   ```
+
+### Reset Admin Password Locally
+
+For local installations of Open WebUI, navigate to the `open-webui` directory and update the password in the `backend/data/webui.db` database.
+
+1. **Generate bcrypt hash** (local machine):
+   ```bash
+   htpasswd -bnBC 10 "" your-new-password | tr -d ':\n'
+   ```
+
+2. **Update password locally** (replace `HASH` and `admin@example.com`):
+   ```bash
+   sqlite3 backend/data/webui.db "UPDATE auth SET password='HASH' WHERE email='admin@example.com';"
+   ```
