What these three things are and why you might need them

Your IP address is a number assigned to your device by your internet provider — it looks like 192.168.1.5 or something similar. Your username is the name you chose to log into a service. Your password is the secret code that proves you own that account. These three pieces of information serve different purposes, and the way you find each one depends on what you're trying to do.

You might need your IP address to troubleshoot a connection problem, set up a home network device, or give to technical support. You might need to recover a username if you've forgotten which email address you used to sign up for something. And you might need to reset a password if you can't remember it. This guide walks you through finding or recovering each one.

Key Takeaways

  • Your IP address appears in your device settings or network status page — Windows users check Settings > Network, Mac users check System Preferences > Network.
  • Your username is usually the email address or account name you chose when you signed up, and you can often find it by checking your email for a welcome message from that service.
  • If you've forgotten your password, use the "Forgot Password" link on the login page rather than trying to find the original — that link lets you create a new one.
  • Never share your IP address, username, or password with someone who contacts you unexpectedly, even if they claim to be from technical support.

Finding your IP address on Windows

On a Windows computer, your IP address is stored in your network settings. Open the Settings app by pressing the Windows key and typing "Settings," then click the result. From there, select Network & Internet on the left side.

Click Wi-Fi if you're connected by wireless, or Ethernet if you're plugged in with a cable. Then click the name of the network you're currently connected to. Scroll down until you see "IPv4 address" — that's your IP address. Write it down exactly as it appears, including all the dots and numbers.

If you need this information quickly and don't want to dig through Settings, you can also open Command Prompt (press Windows key and type "cmd"), type ipconfig, and press Enter. Look for "IPv4 Address" in the results.

Finding your IP address on Mac

On a Mac, click the Apple menu in the top-left corner and select System Preferences (or System Settings on newer versions). Then click Network.

Select the network you're connected to — either Wi-Fi or Ethernet — from the list on the left. Your IP address appears on the right side of the window, labeled as "IP Address." It will be a series of four numbers separated by dots.

Finding your username when you've forgotten it

Your username is usually the email address you used when you created the account, but sometimes it's a different name you chose. The fastest way to find it is to check your email. Look for a welcome message from the service you're trying to log into — these messages almost always include your username or the email address associated with the account.

If you can't find a welcome email, go to the login page for that service and look for a link that says "Forgot username" or "Can't log in?" Click it and follow the instructions. Most services will ask you to enter the email address you think you used, and they'll either tell you the username or send you a link to reset your password (which lets you log in without remembering the username).

If you're trying to find the username for a device on your home network — like a printer or router — check the manual or the sticker on the back of the device. Default usernames for network devices are often "admin" or "administrator," but the specific name depends on the manufacturer.

Resetting a password you've forgotten

Never try to guess or search for your original password. Instead, use the password reset feature on the login page. Look for a link that says "Forgot password," "Can't log in," or "Reset password" — every major service has one.

Click that link and follow the steps. You'll usually be asked to enter your email address or username, and the service will send you a link to create a new password. Check your email (including the spam folder) for that reset link. Click it, create a new password, and you'll be able to log in right away.

Make sure your new password is something you can remember, or use a password manager to store it securely. A password manager is a program that remembers all your passwords for you — examples include Bitwarden, 1Password, and LastPass. This way you only have to remember one master password.

What to do if you can't access the email linked to your account

If you've forgotten your password and you can't access the email address associated with your account, contact the service's support team directly. Go to their website, find the "Contact Us" or "Support" page, and explain the situation. They'll ask you to verify your identity — usually by answering security questions you set up when you created the account, or by providing other information only you would know.

This process takes longer than a straightforward password reset, sometimes several days, so be patient. Keep any responses from support in your email so you have a record of the conversation.

Protecting your IP address, username, and password

Your IP address is generally safe to share — websites and services see it automatically when you visit them. However, never give your username or password to anyone who contacts you, even if they claim to work for the service or your internet provider. Real support teams will never ask for your password.

If someone calls, emails, or messages you asking for these details, it's a scam. Hang up, delete the message, or close the chat. If you're concerned about your account, go directly to the official website yourself and log in to check on it — don't click any links in unsolicited messages.

Frequently Asked Questions

Why does my IP address keep changing?

Most home internet providers assign you a new IP address periodically — sometimes daily, sometimes weekly. This is normal and expected. If you need a permanent IP address for a specific reason, contact your internet provider about a static IP, though this usually costs extra per month.

Is my IP address the same as my Wi-Fi password?

No. Your IP address is assigned by your internet provider and identifies your device on the network. Your Wi-Fi password is something you set up to control who can connect to your wireless network. They're completely separate.

Can someone hack me if they know my IP address?

Knowing your IP address alone doesn't let someone hack your accounts or devices. It's similar to knowing someone's mailing address — it's public information that doesn't grant access to anything. Your passwords are what protect your accounts.

What if I see an IP address that doesn't look like 192.168.1.5?

IP addresses can look different depending on your network setup. Some look like 10.0.0.1, others like 172.16.0.1. As long as it's a series of four numbers separated by dots, it's a valid IP address. If you're unsure whether what you're seeing is correct, take a screenshot and show it to technical support.

Should I write down my username and password somewhere?

Writing passwords on paper or in a notebook is risky if someone finds it. A password manager is much safer — it encrypts your passwords and you only need to remember one master password. If you must write something down, write only the username and keep it somewhere find, then use the password reset feature when you need to log in.
