QuickBooks Password recovers lost or forgotten passwords to password-protected QuickBooks files (*.qbw, *.qba).
There is no way to extract the password, so brute force attack or dictionary search is required to find the password. This may take a lot of time if the password is long and complex. You can use Password Calculator to estimate recovery time. Fortunately it is possible to reset the password to a known one. This can be done instantly and you can open your document immediately. However the original password will remain unknown.
