Comment trouver le mot de passe administrateur sous Windows 10/11

trouver le mot de passe de l'administrateur

Forgetting your Windows administrator password can prevent you from installing software, changing protected settings, or signing in to your PC. If you’re trying to trouver le mot de passe de l'administrateur, however, there is one important thing to know first: Windows does not provide a supported way to display the existing password in readable text.

What you can do is identify the administrator account and use the appropriate recovery method. The correct solution depends on whether you sign in with a Microsoft account, a local account, a Windows Hello PIN, or an account managed by your workplace or school.

This guide explains how to find the administrator account in Windows 10/11 and recover access using Microsoft-supported methods, starting with the least disruptive options before considering a Windows reset. For other situations involving saved credentials, Wi-Fi passwords, browser passwords, or Windows-related login information, see our complete récupération du mot de passe guide.

Peut-on trouver le mot de passe administrateur sous Windows ?

No. Windows does not provide a supported way to reveal the existing administrator password in plain text. The password is protected by Windows rather than displayed through Settings, Control Panel, Credential Manager, or Command Prompt.

If you searched for how to trouver le mot de passe de l'administrateur, you usually need to do one of two things:

Identify which Windows account has administrator privileges.
Reset the password for an administrator account you own or are authorized to manage.

The recovery method depends mainly on whether the account is a Microsoft account or a local Windows account.

Important : If the PC belongs to your employer or school, contact the organization’s IT administrator instead of trying to reset the account yourself.

Quick Answer: How to Recover Your Administrator Password

Use the table below to identify the safest recovery option before changing your Windows account or resetting the PC.

Your Situation	Best Option
You want to see the current administrator password	Windows cannot display the existing password; use a recovery or reset method instead.
You use a Microsoft account	Reset the password through Microsoft’s account recovery process.
You use a local account with security questions	Reset the password from the Windows sign-in screen by answering your security questions.
You previously created a password reset disk	Use the reset disk to create a new local account password.
Another administrator account is available	Use that administrator account to reset the local account password.
You forgot your Windows Hello PIN	Reset the PIN instead; your PIN and account password are different credentials.
None of the recovery options work	Consider Reset this PC as a last resort.
You need a Wi-Fi password, browser password, BitLocker key, or software key	A credential recovery tool such as Magic Recovery Key may help with these related credentials, but not the Windows administrator login password.

Administrator Password vs. Windows PIN

Before resetting anything, make sure Windows is actually asking for your account password. A Windows Hello PIN is not the same as your Microsoft or local account password.

If you normally enter a four- or six-digit PIN to sign in but Windows suddenly asks for a password, select Sign-in options on the login screen and check which credential Windows expects.

If you only forgot the PIN, choose I forgot my PIN when that option is available. If you also forgot the underlying Microsoft or local account password, reset the account password first using the appropriate method below.

Method 1: Reset a Microsoft Account Password

If the administrator account uses an email address to sign in to Windows, it is likely connected to a Microsoft account. In this case, use Microsoft’s official account recovery process rather than trying to find the existing password.

From the Windows sign-in screen:

Sélectionner I forgot my password below the password field.
Verify your identity using the available email, phone, or other security method.
Create a new Microsoft account password.
Connect the PC to the internet and sign in with the new password.

You can also reset the password from another device through Microsoft’s official password reset page.

Conseil : If you can still sign in with a Windows Hello PIN but have forgotten the Microsoft account password, go to Settings > Accounts > Sign-in options > Password and follow the password recovery options.

Method 2: Reset a Local Administrator Password with Security Questions

If you use a local Windows account, you may be able to reset the forgotten administrator password directly from the sign-in screen.

Select the local account on the Windows sign-in screen.
Enter an incorrect password if necessary, then select OK.
Choisir Réinitialiser le mot de passe.
Answer the security questions you configured when the account was created.
Enter and confirm a new password.
Sign in with the new password.

This option is available only when security questions were configured for the local account.

Method 3: Use a Password Reset Disk

If you created a password reset disk before forgetting the local administrator password, you can use it to set a new password without resetting Windows.

Connect the USB drive that contains your password reset disk.
On the Windows sign-in screen, select Réinitialiser le mot de passe.
Choisir Use a password reset disk when the option appears.
Follow the Password Reset Wizard.
Create a new password and password hint.
Sign in using the new password.

A password reset disk must be created in advance and works with local Windows accounts, not Microsoft accounts.

Method 4: Reset a Local Password from Another Administrator Account

If another administrator account already exists on the PC, you can use it to reset the password of a local Windows account.

Sign in to the other administrator account.
Ouvrir Gestion informatique.
Élargir Local Users and Groups > Users.
Right-click the local account whose password you forgot.
Sélectionner Définir le mot de passe.
Enter and confirm a new password.

Then sign out and try logging in to the original account with the new password.

Important : This method applies to local accounts. A Microsoft account password should be reset through Microsoft’s account recovery system instead.

Method 5: Reset Windows as a Last Resort

If Microsoft account recovery, security questions, a password reset disk, and another administrator account are not available, resetting Windows may be the final built-in option.

Before continuing, back up any accessible important data. If Device Encryption or BitLocker is enabled, make sure you have the BitLocker recovery key.

From the Windows sign-in screen, hold Déplacement while selecting Power > Restart.
Accédez à l'environnement de récupération Windows.
Sélectionner Dépannage > Réinitialiser ce PC.
Choisir Conserver mes dossiers if you want Windows to preserve personal files.
Follow the on-screen instructions to reinstall Windows.

Keep my files does not preserve installed applications or system settings. Because resetting Windows makes substantial changes to the PC, use this method only after the less disruptive password recovery options have failed.

Conclusion

If you’re trying to trouver le mot de passe de l'administrateur in Windows 10 or Windows 11, remember that Windows does not provide a supported way to display the existing password. The safest solution is to identify the account type and use the appropriate recovery method.

Start with Microsoft account recovery for an online account. For a local account, try security questions, a password reset disk, or another administrator account before considering Reset this PC.

If the credential you need is actually a saved Wi-Fi password, browser password, software product key, or supported recovery key rather than the Windows login password, Magic Recovery Key can help with those related recovery tasks.

How do I know which account is the administrator?

Open Settings > Accounts > Your info to check the current account, or open Control Panel > User Accounts. Windows normally shows “Administrator” below accounts that have administrator privileges.

Can another administrator reset my password?

Yes, another administrator account can reset the password for a local account through Computer Management > Local Users and Groups > Users. This method does not replace Microsoft's online recovery process for Microsoft accounts.

If it is a Microsoft account, use Microsoft's online account recovery. For a local account, check whether another administrator account is available. If no supported recovery option is available, Reset this PC may be the final built-in solution.
