Users of the popular password manager LastPass are reporting the service is down. Users have been unable to login to the service, making their passwords inaccessible.

Complaints about the apparent service outage started at around 11:30 p.m. EST, with users taking to social media to complain about their inability to connect to the password manager. Reports of the service being down spiked on the website Down Detector , with more than 500 reports that LastPass is down coming in the last hour.

According to users, the issue appears to be affecting all platforms including mobile devices and desktop computers. With the service not responsive, users are unable to retrieve passwords stored in the password manager.

“We are aware of the intermittent connectivity issue and working to address ASAP,” LastPass acknowledged in a tweet. “Our apologies for the inconvenience, and thank you for your patience in the meantime.”

LastPass claimed to have fixed the issue with its service at 12:17 p.m. EST. In a tweet, the company stated, “The intermittent connectivity issue is now resolved. Our team will continue to monitor to ensure full service. Thank you all for your patience, and our apologies again for any inconveniences caused.”

International Business Times has reached out to LastPass for more information.

LastPass, a free password manager with some premium features, boasts at least seven million users. The company was acquired by LogMeIn in 2015 for $110 million.

LastPass is intended to be a service that can generate and securely store a user’s passwords. Instead of requiring a user to remember tens or hundreds of passwords that contain long strings of odd characters, users simply remember a single master password that allows them to login to their account and access the stored passwords.

While the app is often recommended as an additional layer of security, it has run into its fair share of troubles over the years that have made some users turn away from it and seek alternatives.

Last year, Google Project Zero researcher Tavis Ormandy disclosed two security flaws plaguing the popular password manager, including one that would allow an attacker to steal “password for any domain.” LastPass worked quickly to fix the issue, but nevertheless, it existed and put users at risk.

In 2015, LastPass also suffered from a data breach after a hacker was able to gain access to the company’s servers. While LastPass insisted that user information was not stolen, the attackers did gain access to encrypted versions of passwords. The company advised its users to change their passwords after the attack.
