How to Reset or Recover a Lost Microsoft Access Database Password
Question details
The user needs to recover or reset a lost password for a Microsoft Access database in order to regain access and change the password.
- Product
- Microsoft Access
- Device & OS
- not provided
- Scenario
- The user has lost the password used to encrypt an Access database and is currently locked out of the file.
- Observed behavior
- The database file cannot be opened, viewed, or modified because the system prompts for a password that is no longer known.
Verify whether you have any previous backups of this database stored on your local drive, external hard drive, or network folders, as official recovery methods are extremely limited.
Restore the Database from a Known Backup
Because Microsoft does not provide a supported method for password recovery, restoring a previous unencrypted backup is the most reliable way to regain access to your data.
Microsoft intentionally does not include a password reset or recovery tool for encrypted Access databases to maintain high security standards. If a password is lost, the encrypted file cannot be natively unlocked.
Your best course of action is to locate a backup copy of the database from before the password was applied or changed.
Search your local file system, cloud storage (like OneDrive), or company network drives for copies of the .accdb or .mdb file.
Move the backup file to your standard working folder. Ensure you do not overwrite the encrypted version, just in case.
Double-click the backup file to open it in Microsoft Access and verify that the data is accessible and up to date.
Request the Password from the Database Owner or Administrator
If you are working in a corporate environment or using a database created by someone else, the original creator may have a record of the password.

Frequently Asked Questions
Can Microsoft Support help me reset my Access database password?
No. Microsoft strictly states that they do not provide any supported methods, tools, or backdoor services for recovering or resetting a lost Microsoft Access database password.
Are there third-party tools available to recover an Access password?
While various third-party software claims to crack or recover Access database passwords, Microsoft does not support or endorse them. Using unverified tools carries a high risk of malware infection or permanent data corruption.
How do I remove the password if I manage to remember it?
To remove a password you know, open the database in 'Exclusive Mode' (using the Open dialog box). Then, go to the File tab, click Info, and select 'Decrypt Database'. You will be asked to enter the password one last time to remove it.
Does encrypting an Access database encrypt all the data inside?
Yes, when you apply a password to a Microsoft Access database, it securely encrypts the entire file contents. This is why losing the password makes it impossible to view or extract the data natively.
