Password-protect a spreadsheet

You can assign a password to a spreadsheet so only those who know the password can open the spreadsheet.

Require a password to open a spreadsheet

Passwords can consist of almost any combination of numbers, uppercase or lowercase letters, and special keyboard characters.

Tap , tap Set Password, enter the requested information, then tap Done.

When you open a password-protected spreadsheet, you can turn on “Remember this password” so you don’t have to type the password each time you open the spreadsheet.

If you add a password after you share a spreadsheet, be sure to notify collaborators.

Note: Adding a password to a spreadsheet doesn’t encrypt the file.

Change or remove a password

Change a password: With the spreadsheet open, tap , then tap Change Password. Enter the requested information, then tap Done.
Remove a password: With the spreadsheet open, tap , turn off Require Password, type the old password, then tap Done.

Passwords apply to spreadsheets when you share them using iCloud, so your collaborators need the password to open the spreadsheet. A spreadsheet can have only one password. If you change the password when you share the spreadsheet, that becomes the spreadsheet’s only password.

When you add or change a spreadsheet password, the password applies only to versions created after the password was added or changed. To prevent others from restoring unprotected versions or versions with older passwords, stop sharing the spreadsheet, add a password to it, then share the spreadsheet again.
