Where to look first: your setup documents and email
Your administrator username and password are usually in one of three places: the paperwork that came with your device, an email from the person who set it up, or the account you created when you first turned it on. Start by checking your email inbox and any folders labeled "Setup", "Welcome", or "Account" — search for words like "admin", "password", or the device brand name.
If you set up the device yourself, the username is often your own name, your email address, or a variation like "admin" or "administrator". The password is whatever you chose at that time. If someone else set it up for you — a family member, IT person, or business — they should have given you this information in writing or by email when they finished.
Check any printed manuals, quick-start guides, or cards that came in the box. Some manufacturers print a temporary username and password on a sticker attached to the device itself, usually on the back or bottom.
Key Takeaways
- Administrator credentials are usually in setup emails, printed manuals, or on a sticker attached to your device.
- If you created the account yourself, your username is likely your email address or a name you chose, and the password is one you set.
- The person who set up your device for you should have written down or emailed you the username and password at that time.
- If you cannot find the credentials anywhere, you can reset them through your device's recovery or settings menu, though the exact steps vary by device type.
- Never share your administrator username and password with anyone except someone you trust to manage your device.
Checking your device's settings menu
On most devices, you can see what administrator account exists without needing the password. Go to your device's Settings or System Preferences, then look for "Users", "Accounts", "User Accounts", or "People" — the exact name depends on whether you use Windows, Mac, Linux, or another system.
This menu will show you the administrator account name. It will not show you the password, but seeing the username might jog your memory or help you search your email more effectively. If you see an account name you do not recognize, that is the administrator account someone else created.
What to do if you cannot find the password
If you have the username but not the password, you have two options: reset it yourself, or contact whoever set up the device.
Resetting the password yourself is possible on most devices, but the method is different for Windows, Mac, and Linux. On Windows, you can use another administrator account to reset it, or use the password reset disk if you created one when you first set up the device. On Mac, you can use your Apple ID to reset the password, or use Recovery Mode. On Linux, the process varies by distribution.
If you do not have another administrator account and cannot remember your Apple ID password, contact the person who set up the device — they may have a recovery code or backup method. If the device belongs to a business or school, contact your IT department or help desk.
If someone else set up your device and will not share the credentials
If you own the device but the person who set it up will not give you the administrator username and password, you have the right to reset it. The exact process depends on your device type, but it generally involves booting into recovery mode or using a password reset tool.
For Windows, you can use a password reset disk, a Microsoft account recovery option, or third-party password reset tools. For Mac, you can use Recovery Mode and your Apple ID. For Linux, you can boot into single-user mode or use a live USB.
These processes take time and may require you to back up your files first. If you are not comfortable doing this yourself, a computer repair shop can help, though there will be a cost.
Keeping your administrator credentials safe once you find them
Once you locate your username and password, write them down and store them somewhere find — a locked drawer, a password manager, or a safe. Do not email them to yourself, write them on a sticky note on your monitor, or share them with people who do not need them.
If you share a device with family members or colleagues, consider creating separate standard user accounts for them instead of sharing the administrator account. This lets them use the device without being able to install software, change system settings, or access other people's files.
If you think someone has learned your administrator password without permission, change it when ready. Go to your device's user settings, find the administrator account, and select "Change password" or "Reset password".
Different devices, different locations
The steps above work for computers running Windows, Mac, or Linux. If you are looking for administrator credentials on a phone, tablet, router, printer, or other device, the process is different.
For phones and tablets, the administrator account is usually your email address (Google account on Android, Apple ID on iPhone or iPad). For routers and printers, the username is often "admin" and the password is either printed on the device or in the manual. Check the device's manual or the manufacturer's website for the exact steps for your model.
Frequently Asked Questions
Is the administrator password the same as my email password?
No. Your administrator password is for your device or account on that device. Your email password is separate. They may be different even if you used your email address as the username. If you reset your email password, it does not change your device administrator password.
Can I use my device without knowing the administrator password?
Yes, if you have a standard user account. You can log in and use most programs and files. You will not be able to install software, change system settings, or access files owned by the administrator account. If you need to do those things, you need the administrator password or another administrator account.
What if I find the password but it does not work?
Passwords are case-sensitive, so check that capital letters and lowercase letters match exactly. If it still does not work, the password may have been changed since it was written down. Try the password reset process for your device type, or contact the person who set it up.
Is it safe to write down my administrator password?
Writing it down is safer than forgetting it and being locked out of your device. Store the written password in a locked drawer or safe place where only you can find it. A password manager — a program that stores passwords encrypted — is even safer if you are comfortable using one.
What should I do if I think someone else knows my administrator password?
Change it when ready through your device's user settings. Go to Settings or System Preferences, find the administrator account, and select the option to change or reset the password. If you suspect someone has accessed your files, consider backing up important documents and running a security scan.
