Auth0

What is Auth0?
Auth0 is a customer identity and access management platform from Okta. It handles authentication and authorization for web, mobile, and API applications so development teams can add login, SSO, and access controls without building identity infrastructure from scratch.
The platform covers B2C consumer apps, B2B SaaS products, and internal tools. Developers integrate via SDKs and quickstarts for stacks like React, Next.js, iOS, Android, Java, .NET, and Python. Auth0 also ships dedicated tooling for securing AI agents, including user authentication before agent access, Token Vault for scoped API credentials, and fine-grained authorization for RAG pipelines.
Auth0 reports blocking 3 billion-plus attacks monthly across Okta and Auth0 platforms, 99.99% uptime, and 10 billion-plus authentications per month. Customers listed on the site include Siemens, Signify, Zapier, Wyndham Hotels, and the City of Los Angeles.

What is Backengine?
cto.new is a free platform for building apps, agents, and startups on frontier AI models from Anthropic, OpenAI, and others. You can sign up without a credit card or your own API keys, then spin up web and mobile apps, multi-agent teams, and full AI businesses from a single workspace.
