Instead of passing credentials directly to an agent, a 1Password service account is linked to a vault containing the login credentials, and Browserless automatically handles authentication behind the scenes. The demo shows Claude Desktop and Playwright code creating users on a demo app without ever supplying a username or password, relying instead on a profile name tied to the 1Password-backed auto login. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How can I stop my AI agent from seeing my username and password during browser automation? Browserless added an auto login feature that integrates with 1Password service accounts so credentials never pass through the AI agent or automation code. You create a 1Password service account tied to a vault holding the login, add it to Browserless, then create a profile; Browserless itself handles navigating to the login page and entering credentials, so tools like Claude Desktop, Claude Code, Codex, or Playwright scripts only reference a profile name, never the actual username or password. _Developers wiring AI agents into browser automation can track tooling changes like this on daily.dev._ ### How do I use a Browserless auto login profile in Playwright without hardcoding credentials? After creating a Browserless profile linked to a 1Password service account and vault, you connect to that profile's browser session in your Playwright code and skip the login step entirely, navigating straight to authenticated pages like an employee creation form. Browserless auto-detects the login prompt and injects credentials via 1Password behind the scenes, so multiple parallel test profiles can run and log in simultaneously without any credential ever appearing in the script. _Teams automating logins in Playwright can follow tool updates like this via daily.dev._ --- Tags: [#ai-agents](https://daily.dev/tags/ai-agents), [#authentication](https://daily.dev/tags/authentication) [View this post on daily.dev](https://daily.dev/posts/stop-sharing-passwords-with-ai-agents-1password-browserless-auto-login-vldekwhcs) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Stop Sharing Passwords with AI Agents — 1Password + Browserless Auto Login","url":"https://daily.dev/posts/stop-sharing-passwords-with-ai-agents-1password-browserless-auto-login-vldekwhcs","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/stop-sharing-passwords-with-ai-agents-1password-browserless-auto-login-vldekwhcs"},"datePublished":"2026-09-03T14:02:05.953Z","dateModified":"2026-09-03T14:02:26.636Z","description":"A walkthrough demonstrates how to prevent AI coding agents from seeing plaintext usernames and passwords by using Browserless's new auto login feature...","image":"https://i.ytimg.com/vi/1nuqBAtmYhQ/sddefault.jpg","thumbnailUrl":"https://i.ytimg.com/vi/1nuqBAtmYhQ/sddefault.jpg","isAccessibleForFree":true,"articleSection":"Execute Automation","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"Execute Automation","logo":"https://media.daily.dev/image/upload/s--Uh-EE9Cf--/f_auto,q_auto/v1780213688/logos/executeautomation?_a=BAMAMiWQ0","url":"https://daily.dev/sources/executeautomation"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/stop-sharing-passwords-with-ai-agents-1password-browserless-auto-login-vldekwhcs","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"ai-agents,authentication","timeRequired":"PT8M","video":{"@type":"VideoObject","name":"Stop Sharing Passwords with AI Agents — 1Password + Browserless Auto Login","description":"A walkthrough demonstrates how to prevent AI coding agents from seeing plaintext usernames and passwords by using Browserless's new auto login feature...","thumbnailUrl":"https://i.ytimg.com/vi/1nuqBAtmYhQ/sddefault.jpg","uploadDate":"2026-09-03T14:02:05.953Z","duration":"PT8M","url":"https://api.daily.dev/r/VLDEKwHcs","embedUrl":"https://www.youtube.com/embed/1nuqBAtmYhQ"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"Execute Automation","item":"https://daily.dev/sources/executeautomation"},{"@type":"ListItem","position":3,"name":"Stop Sharing Passwords with AI Agents — 1Password + Browserless Auto Login"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/stop-sharing-passwords-with-ai-agents-1password-browserless-auto-login-vldekwhcs#faq","mainEntity":[{"@type":"Question","name":"How can I stop my AI agent from seeing my username and password during browser automation?","acceptedAnswer":{"@type":"Answer","text":"Browserless added an auto login feature that integrates with 1Password service accounts so credentials never pass through the AI agent or automation code.
