How to Set Database Password for MS Access Database File - April 2022
Step 3: In the Open dialog box, select the target database file , then click the downward arrow icon next to Open instead of clicking Open button, and select Open Exclusive from the drop-down. Step 4: When the Access database file opens in Exclusive mode. Then, this proves that your Access database file has been protected by setting database password. Step 3: Browse to your Access database file you'd like to encrypt and then choose it, click the downward arrow icon next to Open , and then select Open Exclusive from the new menu.
Step 5: Enter and verify the new setting password, and then click OK button. Then your Access database file is locked. From now on, whoever wants to open Access database file, which must enter the password. Step 2: Click the Folder icon on the left-top corner. And select your database file in Open dialog box, and click the downward arrow icon next to Open , select Open Exclusive to open the database file in exclusive mode. Then click OK button. Then your Access database file is encrypted.
The next time whoever wants to open the database, will be prompted to enter the password. Note: The Users who attempt to open your Access database file will be denied to access if they do not have the correct password.
In Access , click the Office button and then click the Access Options button. That option is in the Navigation section just below the Application Options section.
Deselecting the Display Database Window option will also disable the Startup command. Users can bypass all these options by holding down the [Shift] key while opening the database. A user can also import objects into a blank database to bypass startup settings. You can use the interface to hide the Database window, but the [Shift] key bypass renders the database vulnerable to anyone who knows about it.
To close the bypass crack, set the AllowBypassKey property to False when the database closes. Automate this process by calling the following code from a close task — just which task is up to you:. After setting this property during the close process, the database will ignore the [Shift] key bypass if one of your users is wily enough to try it. Use this to set any of the startup properties.
For instance, this call hides the Database window:. You can set options when you close or open the database with one exception. The AllowBypassKey property must be set when you close the database. Otherwise, this procedure will generate a reference error. It makes sense that anyone who knows about the [Shift] key bypass 2 might also know how to enabling the [Shift] bypass by resetting the AllowBypassKey property to True.
Someone can try to reset the property, but the effort will fail unless that person is working through the administrator login. A split database is easier to protect than a single database that contains the data and the interface objects. By split, I mean having a database that stores tables and relationships in one database, known as the backend , and the interface objects in a second database, known as the front end.
The two databases communicate through linked tables. There are many reasons to split a database, but this discussion is about just security. To split a database, choose Database Utilities from the Tools menu. Then, select Database Splitter. The wizard will walk you through the process. Anybody who uses Access knows that compacting regularly can mean the difference between a successful application and a bomb.
Compacting makes a copy of the file, overhauls its objects, deletes temporary data, and rearranges the fragmented pieces on your disk. In short, compacting keeps a database in good working order. Starting with Access , Access offers the Compact On Close option, which compacts the database automatically when the last person closes it.
Unfortunately, the process sometimes forgets to clean up after itself. If you find temporary files, with names like db1. Those leftover files can be a problem. There are two ways to protect your database:.
Hiding objects simply keeps them safe from the mistakes an honest user might make, without malice or intent. To hide an object in the Database window or Navigation pane , right-click it and choose Properties.
Then, check the Hidden Attribute option. Now, let me stress one more time to save you the time of complaining that someone who understands Access can unhide these objects just as easily as you can hide them. To view all hidden objects, you simply choose Options from the Tools menu, click the View tab, and then select the Hidden Objects option in the Show section.
In addition, consider hiding only the most important objects. A snoopy user who finds an empty Database window is apt to go looking. In older versions through , assigning the hidden attribute to a table via code is problematic because Access flags the table as temporary. Then, during the next compact, Access deletes it, along with your data! If a user gets that form and clicks Debug, he or she will be staring right into the heart of your application — the module that contains the error-generating code in the VBE.
At this point, the user has full access to your code. On the other hand, in a panic or with a little mischief the user could wipe out all of your code. During the development stage, the ability to access code quickly is a timesaving feature.
As a matter of good practice, all procedures should have some level of error handling to inhibit the generic message and its Debug button.
To password-protect a database, do the following:. Access offers a security feature in the guise of a file format: mde and accde in Access This format is an execute-only version of the database.
You can set rules, but users forget. If you password-protect the feature, the user must enter a login password to regain access to the system.
After the screensaver kicks in step 5 , a user must enter a login password to regain access to the system. If the database is networked, the administrator can set up this protection for everyone who uses the database, saving you the trouble of visiting individual computers.
