  6. You will be asked to link your phone number to your account. This is crucial for account recovery if you lose access to the authenticator.

2. Use a Strong and Unique Password

A strong password is essential for protecting your Steam account. It should be at least 12 characters long and include a mix of uppercase and lowercase letters, numbers, and symbols. Avoid using easily guessable information, such as your name, birthday, or common words.

More importantly, ensure that you use a *unique* password for your Steam account. Do not reuse the same password across multiple websites or services. If one of those websites is compromised, your Steam account could also be at risk.

Tips for Creating a Strong Password:

  • Use a password manager to generate and store strong, unique passwords.
  • Avoid using dictionary words or common phrases.
  • Replace letters with numbers or symbols (e.g., replace "a" with "@" or "e" with "3").
  • Consider using a passphrase instead of a password. A passphrase is a longer, more memorable sequence of words.

3. Regularly Update Your Password

Even with a strong password, it's a good idea to change it periodically, especially if you suspect your account may have been compromised or if you receive a notification of a data breach on another service where you used the same password. Aim to change your Steam password every 3-6 months.

How to Change Your Steam Password:

  1. Log in to your Steam account on the Steam website or within the Steam client.
  2. Click on your profile name in the top right corner and select "Account Details."
  3. Click on "Change my password..."
  4. Follow the on-screen instructions to reset your password. You'll likely need to verify your identity through email or the mobile authenticator.

Phishing attacks are a common way for cybercriminals to steal Steam account credentials. Be cautious of any emails, messages, or websites that ask you to click on links or provide personal information. Always verify the sender's address and be skeptical of any requests for sensitive data.

Red Flags of Phishing Emails:

  • Generic greetings (e.g., "Dear Customer")
  • Poor grammar and spelling
  • Urgent or threatening language
  • Requests for personal information (e.g., password, credit card details)
  • Links that don't match the official Steam website (double-check the URL)

If you receive a suspicious email or message, do not click on any links or provide any personal information. Report the email to Steam support and delete it immediately.

5. Keep Your Computer Secure

A compromised computer can easily lead to a compromised Steam account. Make sure your computer is protected with the following security measures:
