You don't have to share ec2-user SSH keys in the cloud anymore. With Userify, create your team and get going in seconds, and it's free with no credit card needed for up to 20 instances.
Try Userify's web dashboard to manage your team's SSH keys at EC2, and everyone gets their own Linux account, instead of sharing ec2-user. Grant sudo permissions on a whole group of instances just by clicking the "None" permissions and changing to Root or User.
Deploy the shim onto your instances using Ansible, Puppet, Chef, CloudFormation, shell script, or just paste a one-liner. Userify is designed to just work without a lot of fuss.
SSH Key Management
Userify deploys SSH public keys and sudo roles, so you don't have to. No more wasting time with
Role-based Access Management
Color-coded root, user, and zero permissions roles saves you time, and deep flexibility through a powerful API.
Self-hosted or SaaS
For the ultimate in control and security, install Enterprise or Express in your own datacenter or VPC. It even works over finicky or intermittent VPN connections.
Get compliant with PCI DSS 3.2 and the HIPAA Security Rule account requirements, including one user per account. Banish ec2-user forever.
Open Source Shim
The Userify shim is a simple, short Python script that installs with a single command and just uses standard Linux utilities; it wakes up, does its thing, and goes back to sleep.
OpenSSH Power Up!
Not a neutered web-only "SSH" terminal: use all of SSH's normal features and security enhancements like bastion hosts and jump boxes,
scp, SFTP, secure tunnels, VPN, proxying, and forwarding.
Hardened and Secure
Userify is built on modern tech and crypto, including Curve 25519 for data at rest and TLS 1.2 for data in motion, and hardened against XSS, CSRF, inclusion, and injection attacks.
Grows with You
Deploy your shim across multiple clouds and even internal or hybrid datacenters with bad and slow links. As long as HTTPS outbound is available, Userify works. You can even run your own.
Doesn't die, even if the central service (either Userify or a corporate Directory) does, or when network connectivity is broken. Userify will re-sync when the connection is restored.
Users are typically deployed during bootup to a managed server or autoscaled instance within 20 to 40 milliseconds. Changes percolate across all of your nodes within 90 seconds.
Users self-manage keys across entire infrastructure; no more helpdesk calls! Convenient color-coded dashboard lets you manage root and user permissions across your entire cloud with a few clicks.
We started using Userify more than three
years ago across our massive AWS IoT infrastructure. We run
a variety of big data platforms, including Cassandra and
Hadoop on EC2 to process hundreds of data points per second
from hundreds of thousands of devices of multiple
generations. With multiple development teams in multiple
locations, Userify helps us manage our teams across
multiple time zones and languages cleanly and easily, and
even helps get our developers who are sometimes less
familiar with SSH up and running safely without a lot of
help desk support. The Userify architectural and support
teams have been very responsive to our needs and we're
looking forward to what's in store for the
I am just writing to you to tell you how grateful we are to you and your company for the service you provide. In 2014 we looked for a central SSH key management tool and we were really left wanting until we found Userify. We have really enjoyed being part of the process to grow with your company and product as we have found it to be invaluable in increasing our security while making the day to day management of servers that much more convenient. Today we manage servers across 4 continents and I don’t think we would have been able to scale our team and processes as easily without Userify. Looking forward to working with you for years to come!
