How to find apps linked to a phone number on your smartphone

Finding out which apps you’ve signed up for using your mobile phone number can be a bit challenging as there isn’t a universal method for tracking such sign-ups. Here are the things you can do.

Review your login details in your phone’s password manager

Both iOS and Android have built-in password managers that will remember your login details, including the password. If you signed up to an app or an account using your telephone number, you will see it in your password manager.

To access passwords on an iPhone: 

1. Go to “settings.” and scroll down to “passwords.” Log in using your password or biometric information.

2. Scroll down though the list of accounts to see which ones show your phone number rather than your email.

To access passwords on an Android phone:

1. Go to “settings.” and tap “privacy.”

2. Select “auto-fill service from Google” under “advanced.”

3. Tap “passwords.” You need to be logged into your Google account to see this option.

4. Review passwords and logins saved in your password manager, opening the entries one by one, to check if you used a phone number as part of your credentials. 

Review app permissions

Another way to find apps linked to your phone number is by checking your app permissions. 

To check app permissions on an iPhone, follow these steps:

1. Go to “settings.” and tap “privacy & security.”

2. Scroll down and select “app privacy report.”

3. You’ll see a section called “data and sensor access.” Tap “show all” to see what kind of data your apps can access.

4. Check all apps that can access “contacts” as these are more likely to be linked to your phone number.

To review app permissions if you have an Android phone:

1. Go to “settings.” and tap “privacy.”

2. Tap “permissions manager.”

3. Review apps with access to your telephone, SMS, and contacts.

Other methods to find apps connected to your phone number

In comparison to the ones above, the remaining ways to find the apps linked to your number are more tedious and time-consuming.

  1. Check text messages received on your phone: Look through your SMS history for messages from apps. Many apps send a verification code or welcome message to your phone number when you sign up.
  2. Check your apps one by one: Most apps require account registration, and browsing through your list of installed apps can jog your memory about the platforms you’ve signed up for in the past. Moreover, you can also check the apps you no longer use or see by managing your previously downloaded apps.

Review your email: Search your email accounts for welcome emails and account verification emails from apps. Even if you used your phone number, many apps still require an email address.

You’ve likely created hundreds of accounts in online shops, subscription services, and when applying for jobs, so you may only remember some of them. The tips below should help you find the rest.

Search your inbox

Searching your mailbox can help you find forgotten accounts linked to your email. By looking through your inbox, you can locate account verification emails, order confirmations, booking confirmations, feedback, and cancellation emails sent to you in the past.

Use a search engine

Using the search bar on Google or other search engines can be an invaluable tool for locating accounts you created in the past. Try entering your username, email address, or any other relevant keyword associated with these accounts.

Check your password manager

A password manager acts as a centralized repository, ensuring all your login information is organized and easily accessible. Whether it’s a social media platform, an online shopping account, or any other website, your password manager can efficiently remind you of accounts linked to your phone number.

Finding clues in your browser

By checking your browser history and browser’s saved accounts, you can easily access all the websites you have visited and the accounts you have created. Additionally, browsers store favorites, bookmarks, and other traces of past activity.

Go through all the apps on your phone

Most apps require account registration, and browsing through your list of installed apps can jog your memory about the platforms you’ve signed up for in the past. Moreover, you can also check the apps you no longer use or see by managing your previously downloaded apps.

Think twice before sharing anything online

Managing the permissions of your online accounts is crucial in maintaining control over your digital presence. Oversharing data can lead to spam and potential fraud. In fact, this is true when it comes to any data related to your identity. Being mindful of what you share online is the best way to safeguard your personal information and ensure it stays in your hands.
