Auth Agents that reach data behind any login.
Trigger Jobs. Stay Logged In.
Authenticate your users into external sites and create a stable connection your product can rely on.
Establish access even when no API or OAuth route exists.
Enable the workflows that weren’t possible before
Authentication Agents let your product act inside external systems, migrate users seamlessly, and access non-programmable data.
Perform work on behalf of your users
Authenticate into external accounts so agents can take actions directly inside those systems.
Access data to import into your product
Authenticate into external sites to access data buried in reports, dashboards, or other non-programmatic formats.
Migrate customers from another platform
Connect existing accounts at scale and pull the data needed to onboard users seamlessly.
Expertly engineered for the hardest login flows
Auth Agents are built by a team with years of experience authenticating into complex, login-gated systems. They deliver reliable performance across verification challenges and modern bot defenses that typically slow or interrupt automated access.
MFA and verification flows: Support for SMS, app-based, and email verification without user friction.
Adaptive CAPTCHA handling:
Automatic navigation of common CAPTCHA patterns across diverse sites.
Anti-bot defense navigation: Reliable authentication through systems designed to block automation.
How it Works
1. User selects the account to connect
Your product presents a list of available connection options and the user chooses the external source they want to link.
2. User enters credentials securely
A secure interface collects the credentials and Deck handles the full authentication flow, including verification steps when required.
3. Deck returns a connection token
Once authenticated, Deck provides a connection token your product can use to run agents, fetch data, and perform actions over time.
Authentication built to match your stack
Whether you want a fast UI, a custom experience, or a headless flow, each method delivers a stable connection to the external system.
Auth SDK
A drop-in UI component that handles authentication end to end, including MFA and verification flows. This is the fastest way to add external account connections to your product.
Custom UI
Use the same API endpoints the Deck team uses to build a fully custom authentication experience that matches your brand and user flow.
Headless Auth
Authenticate without a UI when your product owns the credentials and does not need users to enter them directly.
Authless Auth
Establish a connection to an external system when no login is required. Useful for lightweight integrations that do not need an Auth Agent.

Security is built into every connection
Deck manages user credentials end to end, removing the need for your product to handle or store sensitive information. All authentication is encrypted, isolated, and governed by SOC 2 Type II and HIPAA practices for secure, long-term access.
