Quick answer
For most computers and phones, start in Settings and look under Accounts, Sign-in Options, Security, or Passcode. For web services, open the account's Security settings. If you need to protect files rather than an account, built-in document tools work one file at a time, while dedicated file-security software can protect groups of folders and files together.
A password can protect very different things. Your Windows or phone password controls access to a device session. A Google, email, or Apple password protects an online account. A document password controls access to a specific file. Knowing which layer you are changing prevents you from updating one password while leaving the information you actually care about exposed somewhere else.
For example, changing a laptop password does not automatically replace the password on your Gmail account, and changing an email password does not add encryption to documents already saved on the computer.
Device level
Computers and phones: Windows sign-in, iPhone passcode, Mac account password, and similar controls.
Account level
Web and app services: Google, Gmail, Apple Account, cloud storage, and other online logins.
File level
Documents and folders: Word encryption, encrypted archives, protected folders, and secure file containers.
Windows & computer access
Update a Windows or computer sign-in password
On Windows 10 and Windows 11, the normal route is through account sign-in settings. The exact labels can differ slightly between versions, but the password control remains under the user account's sign-in options.
Change your Windows 10 or 11 login password
Open Start and choose Settings.
Go to Accounts, then open Sign-in options.
Under Password, select Change.
Enter your current password, type the new password twice, and add a hint if Windows asks for one.
Reset another local Windows account as an administrator
If you administer the computer and need to set a new password for a local account, Windows also supports the net user command. Open Command Prompt with administrator rights before using it.
net user [username] [new_password]
Important: use this only on an account and computer you are authorized to administer. Replacing a local account password can affect access to credentials or encrypted material tied to the previous sign-in state.
Online accounts
Change passwords for Google, Gmail, and Apple
Online-account passwords usually affect more than one app. A Google password, for example, applies to the Google Account used by Gmail, Drive, YouTube, and other Google services. An Apple Account password is likewise separate from the passcode used to unlock an iPhone or iPad.
Update your Google or Gmail password
Changing the password for Gmail changes the password for the Google Account connected to it.
Open myaccount.google.com and sign in.
Select Security, then find the section for signing in to Google.
Choose Password and verify your identity when prompted.
Enter and confirm the new password, then select Change Password.
On Android, you can also tap your profile picture in a Google app, choose Manage your Google Account, and open the Security tab.
Update an iPhone, iPad, or Apple Account password
Your device passcode and your Apple Account password serve different purposes, so choose the setting that matches what you want to change.
iPhone or iPad passcode: Settings → Face ID & Passcode or Touch ID & Passcode → Change Passcode.
Mac account password: Apple menu → System Settings → Users & Groups → account information → Change Password.
Documents & local files
Replace passwords on documents and protected files
File protection is separate from your computer login. If a Word document already has encryption enabled, you change that password from inside Word. If you need to secure many files or folders, a dedicated encrypted container can be more practical than setting a different document password one file at a time.
Change the password on a Microsoft Word document
Open the document and go to File → Info.
Select Protect Document and choose Encrypt with Password.
Replace the existing password with the new one, then confirm and save the document.
Word's built-in option is useful for individual documents, but it is not designed for batch-protecting a large folder. For broader Windows file-protection options, the existing guide also references Avast's Windows file and folder protection guide.

File-level recommendation
When many files need one protection workflow
For Windows or online-account passwords, the built-in settings are the right place to make the change. When the task is protecting many local documents and folders together, the existing site recommends Folder Lock because it combines a master-password workflow with 256-bit AES encrypted lockers and drag-and-drop file handling.
The lock workflow restricts access and keeps protected items out of ordinary Windows browsing while protection is active. This is faster than assigning a separate password to every document.
256-bit AES encrypted lockers
Encrypted lockers act as protected storage areas. Files added to a locker are encrypted and made available again when the locker is opened with the correct credentials.
Carry protected files on removable storage
Portable lockers are intended for moving protected data on USB and external drives so the secured collection can travel with the device. The existing site also links to an independent USB Secure listing.
Remove sensitive files more deliberately
The shredding feature is designed to overwrite deleted data rather than relying only on normal file deletion, which can leave recoverable traces behind.
Use companion apps and cloud-linked lockers
The product family includes Android and iOS apps and locker workflows associated with services such as Google Drive, Dropbox, and OneDrive. The original Android destination is preserved at Google Play.
Batch workflow
Protect several files with one master-password workflow
Instead of creating a different password for every Word file, a folder-level tool lets you place a group of documents behind one protected workspace.
Install the software and create the master password. Treat it as critical recovery information because the product is designed without a simple password backdoor.
Open the file or folder locking area. Choose the protection feature intended for local files.
Add the folder that contains the documents. Drag-and-drop keeps the workflow practical when many files need the same protection boundary.
Turn protection on and verify the result. Confirm the files are no longer accessible from their normal location until you unlock them.
Troubleshooting
Fix common password-change problems without losing data
Forgot your Windows sign-in password?
For a Microsoft Account, use the recovery option shown on the Windows sign-in screen and complete the identity-verification steps by email, phone, or another available recovery method. For a local account, Windows may offer security questions or a password reset disk if those were configured beforehand.
Forgot a Word document password?
Microsoft's document encryption is intentionally strict; Word does not provide a normal “forgot password” link that reveals or resets the existing document password. Keep the password or recovery information in a secure place before encrypting important files.
Changed Yahoo credentials but iPhone Mail still asks for the old password?
Change the password in Yahoo Account Security first. Then return to the mail account settings on the iPhone and authenticate again with the new credentials when prompted.
Need a different password for Google Photos Locked Folder?
Google Photos Locked Folder uses the supported device screen lock rather than a separate folder password. Change the device's lock method if you need to change the credential used to open Locked Folder.
Planning to remove a mobile vault app?
Export, restore, or synchronize important protected files before uninstalling. Removing a security app can also remove locally stored vault data, depending on how the app stores its protected content.
The existing page describes the full version as a one-time purchase rather than a subscription and also notes a Lite edition for basic folder hiding without encryption.
User experience
Why a single protected vault can simplify document security
“I used to maintain separate passwords across several Word files. Moving sensitive documents into one protected vault reduced the number of credentials I had to manage while keeping the files together.”
Frequently asked questions
Answers about device, account, and document passwords
On Windows, open Settings → Accounts → Sign-in options. On a Mac, use System Settings → Users & Groups. On phones and tablets, open the device security, biometric, or passcode settings that control screen access.
No. Services run by different providers must be updated individually because they do not share one password-control system. A password manager can make it easier to create and store a different password for each account.
An open password prevents someone from viewing the document without the password. A permissions password can allow the file to be opened while restricting actions such as editing, copying, or printing.
Word does not provide a built-in batch-password command for many documents. If multiple files need one protection boundary, encrypt or lock the parent folder with an appropriate file-security tool.
No. A standard password controls who can open the content, but it does not stop an authorized viewer from capturing the screen. Screenshot restrictions require specialized rights-management or anti-copy technology.
Next step
Keep account passwords current, then protect sensitive local files separately
Once your Windows, Google, Gmail, or Apple credentials are updated, review the documents stored on the device. If several sensitive folders need the same protection workflow, an encrypted locker can be easier to manage than separate passwords on every file.
