OPenClaw Beginner's Guide: Account Registration & API Key Binding Step by Step

If you're new to OPenClaw, the registration and API key binding process might feel overwhelming at first. But don't worry—it's simpler than it looks. Follow this guide step by step, and you'll have everything up and running in about ten minutes. This article is tailored for beginners, walking you through the entire process from account registration and login to API key binding.

Two Ways to Register an OPenClaw Account

When you visit the OPenClaw website, you'll see two registration options: email and Google account. With email registration, you'll need to enter a valid email address and set a password. Then check your inbox for a verification email and click the link to activate your account. Using a Google account is faster—just authorize the connection, and your account is automatically created without the email verification step. We recommend choosing Google account sign-up, as it also makes it easier to link other services later.

When setting your password, make sure it's at least 8 characters long and includes both uppercase and lowercase letters and numbers. If you don't receive the verification email, check your spam folder or try a different email address. Note that each email can only be used to register one account, so don't attempt multiple registrations with the same email.

Login & Security Verification Setup

After registration, return to the login page, enter your credentials, and you'll access the dashboard. On your first login, you'll be prompted to set up two-factor authentication (2FA) to protect your account. We recommend using free apps like Google Authenticator or Authy to scan the QR code and generate time-based codes. Once set up, you'll need to enter a verification code each time you log in. While it adds an extra step, it significantly reduces the risk of account theft.

If you'd like to skip the 2FA code on your personal device, you can select "Trust this device" in the security settings. However, never enable this option on a public computer. After logging in, we suggest updating your default nickname and completing your profile to make team collaboration easier later on.

Generating & Binding an API Key

Your API key is the core credential for calling OPenClaw's interface. In the left sidebar of the dashboard, find the "API Keys" option and click "Create New Key." The system will generate a string of characters. This key is only displayed once—be sure to copy and save it in a secure location. If you lose it, you'll have to generate a new one, and the old key will be immediately invalidated.

To bind the key, choose the method that matches your development environment. If you're using command-line tools, you can paste the key into the config file. For web applications, configure it using the SDK provided by OPenClaw. A common mistake is accidentally including extra spaces or line breaks before or after the key—always double-check when pasting. Once the key is successfully bound, the dashboard will show a "Key Activated" message, and you can start calling the API.

Switching Accounts & Logging Out

Each OPenClaw account can only be logged into one terminal at a time. If you need to switch accounts, you must log out of the current session first. At the bottom of the settings page, you'll find the "Log Out" option—click it and confirm. Note that logging out doesn't delete your data; it simply ends the current session. When you log back in, just enter the email and password of the new account.

If you manage multiple API keys, it's a good practice to create a separate key for each project in the dashboard and set the appropriate permission scope. That way, if one key is compromised, only that project is affected—not your entire account. To switch between keys, simply replace the key string in your code; no need to log out of your account.
