Password manager Dashlane has confirmed that hackers used brute force attacks to compromise approximately 20 user password vaults. Multiple users report being locked out of their accounts following login attempts from unfamiliar locations and devices.
Dashlane disclosed the security incident after users experienced unauthorized access attempts on their accounts. The attacks involved repeated login tries—a brute force method—targeting a limited number of password vaults stored on the platform.
Affected users received notifications of login attempts from distant geographic locations and unrecognized devices. Dashlane locked these accounts as a security measure to prevent further unauthorized access.
What happened
The brute force attacks exploited weaknesses in account authentication, allowing attackers to attempt numerous password combinations until gaining access. While Dashlane has not disclosed the exact number of compromised accounts, the company confirmed approximately 20 password vaults were stolen during the incident.
Company response
Dashlane has not yet published a detailed public statement about the full scope of the breach or remediation steps. Users locked out of their accounts are being directed to recover access through the company's standard recovery procedures.
What users should know
Password manager breaches carry heightened risk, as compromised vaults potentially expose credentials for multiple services. Users with Dashlane accounts should:
- Change passwords for critical accounts, particularly email and financial services
- Enable multi-factor authentication where available
- Monitor accounts for suspicious activity
- Consider using a different password manager if trust has been affected
This incident highlights ongoing security challenges facing password management platforms, which remain high-value targets for attackers. The relatively small number of compromised vaults suggests Dashlane's security measures contained the breach, though questions remain about how attackers obtained credentials for the targeted accounts.
Dashlane has not announced whether the attack exploited a vulnerability in its service or relied on compromised credentials obtained elsewhere.
