LastPass is warning users about a phishing campaign that uses fake email alerts claiming they must back up their account within 24 hours. The emails are designed to push recipients to a fraudulent page that asks for their LastPass master password, according to a report from Infosecurity Magazine.
The company said the messages are not legitimate and stressed that it would never require users to back up their account through an email prompt. That point matters because the campaign relies on urgency and brand impersonation rather than a software flaw. There is no indication of a new LastPass product vulnerability tied to this activity.
The risk is significant because a master password protects access to a user’s password vault. If attackers can capture that credential, they may be able to attempt account takeover and gain access to other stored logins, depending on what additional information they collect. For business users, that could extend beyond personal accounts to shared or work-related credentials.
The campaign also shows why password managers remain attractive phishing targets: one successful lure can expose many accounts at once. Security teams should remind users not to click account-action links in unsolicited emails, especially messages that demand action on a short deadline. Instead, users should open LastPass directly through the official app or typed website address, verify any account notices there, and keep multi-factor authentication enabled. Using a trusted VPN on public networks can reduce other forms of exposure, but it will not prevent credential phishing if a user submits their password to a fake site.
For LastPass, the immediate issue is user protection and trust. For users, the takeaway is simpler: any email claiming your vault needs an emergency backup should be treated as suspicious unless confirmed through LastPass’s official channels.
