Ory Kratos Features

Most software applications need to deal with user and identity management. Ory Kratos serves common flows, so you don't need to rewrite everything yourself.

Self Service Login and Registration

Enable users to create and sign in to accounts using username/email and password combinations, Social Login, passwordless flows and more.

User Management

Manage your userbase and get, create, update or delete identities and their data.

Bring Your Own UI and Identity Models

Use customizable identity models (defining custom fields such as name, address, favorite pet) and create your own user interfaces for flows in your style and branding.

Profile and Account Management

Let your users use secure flows to update passwords, personal details, email addresses, linked social profiles and more.

Social Logins

Simplify your users' experience and let them use their existing accounts at Google, GitHub, Apple, etc. to sign up and log in. All OIDC providers are supported.

Account Verification and Recovery

Verify an identity by checking the email, phone number, or physical address of that user. Provide recovery of accounts using "Forgot Password" flows, security codes, etc.

We chose the Ory Stack to develop an internal IAM. Ory is ideal because we could customize it exactly how we needed to and could build a flexible system for authorizing user actions.
