Mitro was a password manager for individuals and teams that securely saved users' logins, and allowed users to log in and share access.
On October 6, 2015, the Mitro service shut down.
The successor to Mitro is named Passopolis; this is a password manager built upon the Mitro source code.
Mitro was founded in 2012 by Vijay Pandurangan, Evan Jones, and Adam Hilss.
The Mitro team announced the shuttering of the Mitro service with the following timeline:
The Mitro team explained the reason for shutting down the service was that the cost and administrative burden to maintain the service in their spare time with their own money had become too much. Given that they could not properly manage a service that people rely on for their security, they needed to stop running it.
Mitro uses Google's Keyczar on the server and Keyczar JS implementation on the browser.
