Agent Identity

Overview

Browserbase Identity helps your agents access sites as legitimate, authorized participants by providing them with a verifiable identity trusted by websites along with authentication features and configurable web access mechanisms such as proxies or CAPTCHA solving.

Access

Use these Identity features to help your agents access protected sites.

Verified

Use Browserbase’s purpose-built Chromium browser with real fingerprints for protected sites.

Web Bot Auth

Identify your browser traffic with cryptographic signatures so participating websites can recognize it.

CAPTCHA solving

Solve supported CAPTCHA challenges in your browser sessions.

Proxies

Route browser traffic through residential or datacenter proxies.

Human verification with AgentKit

Prove that your agent is human-backed in x402 sessions.

Authentication

Manage credentials and interactive sign-in flows for your browser sessions.

Authentication management

Handle 2FA, OAuth flows, and other authentication challenges in browser sessions.

1Password credentials

Retrieve credentials from your 1Password vault without hardcoding them.

Verified

Verified sessions use a purpose-built Chromium browser with real browser fingerprints that Browserbase’s bot protection partners recognize. This can provide higher success rates and fewer interruptions than standard browser sessions.

Browserbase offers Verified on the Scale plan. You can still build a proof of concept with standard browsers and proxies. Contact [e-mail] to trial Verified or discuss an upgrade.

Key benefits:

• Bot protection partners recognize sessions as legitimate
• Significantly fewer CAPTCHA challenges
• Reliable access to protected sites
• Real browser fingerprints - not randomly generated configurations

Node.js

SDK

import Browserbase from "@browserbasehq/sdk";

const bb = new Browserbase({apiKey: process.env.BROWSERBASE_API_KEY!});

const session = await bb.sessions.create({
  browserSettings: {
    verified: true,
  },
  proxies: true,
});
console.log(session);

Python

SDK

from browserbase import Browserbase
import os

bb = Browserbase(api_key=os.environ["BROWSERBASE_API_KEY"])

session = bb.sessions.create(
    proxies=True,
    browser_settings={
        "verified": True,
    },
)
print(session)

Web Bot Auth

Web Bot Auth gives participating websites a cryptographic identity signal for your browser traffic. Websites verify the signature and apply their own access policies. A valid signature doesn’t grant access or sign your agent into a user account.

Browserbase offers Web Bot Auth in beta. Learn how it works and request access.

Best practices

Use these practices to keep browser-agent workflows stable, efficient, and responsible.

Site compliance and ethical use

Before your agent accesses a website:

• Review the site’s terms of service to ensure compliance.
• Check robots.txt for crawling guidelines when applicable.
• Cache responses to reduce unnecessary requests and improve efficiency.
