password protected spreadsheet
My password protected numbers spreadsheet has recently started opening without the need for a password. I was able to reset the password and it worked for awhile and now it is back to opening without the password. It is stored on the cloud if that makes a difference. I happens on a new mac mini running Ventura 13.3 and numbers 13.0. I am wearing my Apple watch which unlocks my computer automatically if that makes a difference.
Any ideas why this spreadsheet is no longer secure?
