<paragraph xml-lang="en-US" id="par_id3153368" role="paragraph">In <item type="productname">%PRODUCTNAME</item> Calc you can protect sheets and the document as a whole. You can choose whether the cells are protected against accidental changes, whether the formulas can be viewed from within Calc, whether the cells are visible or whether the cells can be printed.</paragraph>
<paragraph xml-lang="en-US" id="par_id3145261" role="paragraph">Protection can be provided by means of a password, but it does not have to be. If you have assigned a password, protection can only be removed once the correct password has been entered.</paragraph>
<paragraph xml-lang="en-US" id="par_id3148576" role="paragraph">Note that the cell protection for cells with the <emph>Protected</emph> attribute is only effective when you protect the whole sheet. In the default condition, every cell has the <emph>Protected</emph> attribute. Therefore you must remove the attribute selectively for those cells where the user may make changes. You then protect the whole sheet and save the document.</paragraph>
<warning id="par_id5974303">These protection features are just switches to prevent accidental action. The features are not intended to provide any secure protection. For example, by exporting a sheet to another file format, a user may be able to surpass the protection features. There is only one secure protection: the password that you can apply when saving an OpenDocument file. A file that has been saved with a password can be opened only with the same password.</warning>
