How to Check if Your Password Has Been Stolen

How to Check if Your Password Has Been Stolen

Here we can see, “How to Check if Your Password Has Been Stolen”

Passwords have been leaked on several websites. As a result, attackers can “hack” your accounts by downloading databases of usernames and passwords. This is why you should never reuse passwords for important websites because a single site’s leak can provide attackers with all the information they need to log into other accounts.

Have I Been Pwned?

Have I Been Pwned, a website run by Troy Hunt, keeps track of the username and password combinations obtained from public leaks. These are from publicly available breaches that can be found on the internet or the dark web. This database makes it easier to check them yourself without navigating to the more dangerous parts of the internet.

  • Go to the main Have I Been Pwned? Page and search for a username or email address to use this tool. The results will tell you if your username or email address has ever been exposed in a database breach. To check multiple email addresses or usernames, repeat the process. You’ll be able to see which leaked password dumps your email address, or username appears in, which will provide you with information about potentially compromised passwords.
  • Click the “Notify me” link at the top of the page and enter your email address to receive an email notification if your email address or username appears in a future leak.
  • You can also lookup a password to see if it has ever been exposed in a leak. Go to the Have I Been Pwned? website’s Pwned Passwords page, type a password in the box and then click the “pwned?” button. lYou’ll be able to see if the password has been seen in any of these databases, as well as how many times it has been seen. You can do this as many times as you want to check more passwords.

Warning: If a third-party website asks for your password, we strongly advise you not to type it in. If the website isn’t trustworthy, these can be used to steal your password. Instead, we recommend only using the Have I Been Pwned? The site, which is well-known and explains how your password is safeguarded. 1Password, a popular password manager, now has a button that uses the same API as the website, so hashed copies of your passwords will be sent to this service. This is the service you should use if you want to see if your password has been leaked.

We recommend changing any important passwords you use right away if they have been leaked. In addition, it would help if you used a password manager to make creating strong, unique passwords for all of your important websites a breeze. Two-factor authentication can also help protect your important accounts by preventing attackers from accessing them without a second security code—even if they know the password.


  • LastPass Security Challenge includes a feature similar to this. To access it from a LastPass browser extension, click the LastPass icon on your browser’s toolbar, and then select More Options > Security Challenge.
  • LastPass discovers a list of email addresses in your database and asks if you want to see if any of them have ever been exposed in a leak. If you agree, LastPass will check them against a database and notify them via email if there are any leaks.
  • LastPass also has a section dedicated to “Compromised” passwords. This list shows you which websites have experienced security breaches since you last changed your password, indicating that your password may have been compromised. Any sites that appear here should have their passwords changed.

  • The 1Password password manager’s web-based version can now check if your passwords have been leaked as well. 1Password makes use of the same Have I Been Pwned? Service that we discussed previously. It includes a built-in “Check Password” button that sends the password to the service and receives a response. To put it another way, it works in the same way that the Have I Been Pwned? Website does.
  • If you have a 1Password account, you can use this service by logging in to your account at After clicking “Open Vault,” select one of your accounts. You’ll see a “Check Password” button if you press Shift+Control+Option+C on a Mac or Shift+Ctrl+Alt+C on Windows, which checks if your password is in the Have I Been Pwned? Database. Because it’s a new, experimental feature, it’s currently hidden, but it should be better integrated into future versions of 1Password.
  • In the future, this feature will be integrated into 1Password’s Watchtower feature. The Watchtower feature in 1Password warns you if any of your saved passwords are potentially vulnerable and require a password change.

The most important thing you can do for important websites is not to reuse passwords. Your email, online banking, shopping, social media, business, and other critical accounts should all have their unique passwords so that a data breach on one site does not compromise your other accounts. Password managers make it possible to create strong, unique passwords without remembering a hundred different ones.

User Questions:

  1. How does Google know my password has been compromised?

Chrome sends a copy of your usernames and passwords to Google using a special form of encryption to see if you have any passwords that have been compromised. This allows Google to compare them to lists of compromised credentials, but Google cannot deduce your username or password from this encrypted copy.

  1. Why is my iPhone telling me my passwords have been compromised?

Your iPhone will send you a notification with the title Compromised Passwords if one of your passwords matches a password found in a data leak. In practice, this means you should change the password on the account or accounts in question right away to avoid future security issues.

  1. Are passwords secure on iPhone?

Your passwords are also securely monitored by iPhone, which notifies you if they appear in known data leaks. Turn off Detect Compromised Passwords in Settings > Passwords > Security Recommendations if you don’t want iPhone to monitor your passwords.
