Packaging and signing databases
If you want to convey to users of a database executable file that they can trust the file,
use the Package And Sign tool to create an Access Deployment (.accdc) file. An .accdc
file contains one database that has been compressed. The file is signed by using a
digital signature, signifying that no changes have been made since the package was
created.
TIP You can purchase a digital signature from a third-party company. For information,
search for digital signature in Access Help.
To package the current database as a signed .accdc file:
1 With all database objects closed, display the Save As page of the Backstage view.
2 In the Advanced area of the right pane, double-click Package and Sign .
3 When a security message asks you to confirm that you want to use the installed
certificate, click OK .
In the Create Microsoft Access Signed Package dialog box, specify a location for
the package and assign a name. Then with Save as type set to Microsoft Access
Signed Package , click Create .

To use the packaged file:
In File Explorer or Windows Explorer, navigate to the location in which the signed
ACCDC database is stored.
