{{Main|Microsoft Office password protection}}
Microsoft Office has a security feature that allows users to encrypt Office (Word, Excel, PowerPoint, Access, Skype Business) documents with a user-provided password. The password can contain up to 255 characters and uses [[Advanced Encryption Standard|AES]] 128-bit advanced encryption by default.<ref>{{Cite web |title=Password protect documents, workbooks, and presentations |url=https://support.office.com/en-us/article/Password-protect-documents-workbooks-and-presentations-ef163677-3195-40ba-885a-d50fa2obb6b68#bm1 |access-date=February 6, 2015 |website=Microsoft Office Support}}{{Dead link|date=November 2019 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> Passwords can also be used to restrict modification of the entire document, worksheet or presentation. Due to lack of document encryption, though, these passwords can be removed using a third-party cracking software.<ref>{{Cite web |title=Unprotect a Word Document |url=https://superuser.com/a/96244 |access-date=March 9, 2017 |website=superuser.com |archive-date=November 1, 2018 |archive-url=https://web.archive.org/web/20181101140147/https://superuser.com/questions/96242/unprotect-a-word-document/96244 |url-status=live }}</ref>
