Preparing Your Thomson Reuters Access

Effortless Entry to Your Professional Platform

  1. Navigate to the official Thomson Reuters OnePass sign-in page, often found on product-specific login screens (e.g., for ProView or Westlaw) or directly via the main Thomson Reuters website.
  2. Enter your registered username (which is usually your email address) into the designated field.
  3. Type your secure password into the password field. Be mindful of case sensitivity.
  4. You may see an option to 'Save username' or 'Save username and password'. Consider your device's security before enabling these options.
  5. Click the 'Sign in' button to proceed.
  6. If you have Two-Factor Authentication (2FA) enabled, you will be prompted to complete the second verification step (e.g., via biometric scan or authenticator app code).

Unlocking Your Professional Resources

When Account Access Becomes Challenging

⚠️ Forgot Password

Cause: You have forgotten your password or need to reset it for security reasons.

Solution: From the Thomson Reuters Account or specific product sign-in screen, select 'Reset your password'. Enter your email address and click 'Send link'. Check your email inbox for a password reset request. Follow the link, then enter and confirm your new password twice. Remember, your new password must meet the strong password criteria.

⚠️ Forgot Username

Cause: You cannot recall the email address or username associated with your OnePass account.

Solution: On the sign-in page, look for the 'Forgot username?' link. Follow the instructions provided to retrieve your username. This typically involves entering an associated email or other identifying information.

⚠️ Account Locked

Cause: Your account may be temporarily locked due to multiple failed login attempts or specific security protocols.

Solution: If your account is locked, an administrator might need to approve a password reset. For Single Sign-On (SSO) firms, only an administrator can initiate password resets for locked accounts. Contact your firm's administrator or Thomson Reuters support for assistance.

⚠️ Password Not Accepted

Cause: The new password does not meet the required complexity or rules.

Solution: Ensure your password is at least 8 characters long and contains at least three of these four character types: lowercase letters (a-z), uppercase letters (A-Z), numbers (0-9), and special characters (!@#$%^&*). Also, avoid using easily guessed words or phrases, and do not include your sign-in name within the password.

Answers to Your Thomson Reuters Portal Questions

Q: How can I access my Thomson Reuters eBooks?

You can access your Thomson Reuters eBooks through the ProView platform, which is integrated with your OnePass account. Simply log in to ProView using your OnePass credentials to view your digital library.

Q: What is Thomson Reuters OnePass?

OnePass is a single sign-on solution from Thomson Reuters that allows you to use one set of credentials (username and password) to access multiple Thomson Reuters products, such as Westlaw, Practical Law, and ProView, streamlining your login experience.

Q: Why is my Two-Factor Authentication (2FA) not working?

If your 2FA isn't working, first ensure your authenticator app is synced correctly or your biometric device is properly registered. Note that email as a standard 2FA option is being deprecated as of November 14, 2025. Thomson Reuters recommends using biometrics or Authenticator apps like Auth0 Guardian for a more secure and reliable experience.

Q: Who can change user IDs for Thomson Reuters accounts?

User IDs cannot be changed. Only a firm administrator has the authority to add or remove users from an account. No one, including administrators or Thomson Reuters support, can access or view your password.
