Instinct AI Introduces Secure Phone-Based Website Logins for Agents

Users log into sites via phone webview so session cookies transfer to the agent.

Ronith posted that Instinct built a phone-based method for signing agents into websites. The process opens a webview on the user's device for login, then moves the resulting cookies to the agent's system. Multiple replies note that passwords stay off the agent side entirely. Users including Xiaoyin Qu and Kushal Byatnal highlighted reliable Google sign-ins to services such as LinkedIn and Notion, parallel task handling, and proactive behavior. Other posts observed that some sites may still block the logins or flag IP shifts.

We built the most secure, simple way to sign an agent into websites from your phone. The agent never receives your password. Not in the chat, not in the logs. This works across all sites, and any sign in patterns.

someone needs to build a 1Password for agents browsing the web, where they can have your passwords and passkeys to securely login on your behalf and use the web

Been reading all these posts about Instinct but no one really explained why it was so good. Just onboarded yesterday. The magical part is that it’s proactive. Lots of assistants can execute tasks. Instinct predicts what’s going to matter and asks you if you want it solved…

For those who want to understand how this works: 1) They open a webview with the site they want you to login to 2) You login to that site, creating some cookies 3) They transfer those cookies to their agent’s computer 4) Now your agent can access that site Surprised no one did…

  @anshnanda Many sites will block DC logins, or changes to IP during a login. Still pretty fragile. And unless they are using a TEE, they can access your logins.
