Cybersecurity and password service provider 1Password LLC today announced a new partnership with artificial intelligence search startup Perplexity AI Inc. to bring 1Password’s credential management, secure autofill and access controls into Perplexity’s Comet browser.

Under the partnership, 1Password and Comet users can install the 1Password browser extension to log in, autofill credentials and securely access their accounts as they navigate the “AI-powered internet.” The partnership is also part of a commitment from 1Password to make AI adoption secure by default.

“The internet is entering a new chapter, one where AI is woven into everything we do,” explains Anand Srinivas, vice president of product and AI at 1Password. “No matter how intelligent our tools become, they only succeed if people can trust them. Partnering with Perplexity on Comet shows what’s possible when AI and security are designed to work together from the start: an online experience that’s powerful, seamless and safer for everyone.”

The 1Password integration sees the company offering a Comet-compatible browser extension, available for free to all 1Password customers, enabling safer and effortless access to their credentials.

1Password says its browser extension offers Comet users privacy-first browsing, where credentials stay private, even when engaging with AI features. There’s also seamless autofill, with support to sign in with usernames, passwords and two-factor authentication codes in seconds. Moreover, it offers safer access with end-to-end encryption that protects sensitive accounts, as well as stronger protection, with the ability to generate and save strong, unique passwords and passkeys. And there’s support to sync everywhere and use saved credentials across devices, operating systems and browsers.

“Comet is designed to make AI-powered browsing effortless and productive, but that experience only works if security is also built in from the start,” said Dmitry Shevelenko, chief business officer at Perplexity. “1Password stands apart in making security simple, combining privacy, transparency and usability in a way that delivers both trust and a seamless user experience. Together, we’re bringing an internet experience that is effortless, productive and secure by default.”

1Password says that the collaboration with Perplexity on the Comet browser reflects its approach to AI security that is grounded in privacy, transparency and trust. Secrets stay secret with end-to-end encryption and a zero-knowledge architecture and users maintain clear control over what AI can access, when and why.

The Comer browser is currently only available to paid Perplexity subscribers, PayPal and Venmo users in some markets and students via SheerID verification and is not available to the broader public. However, with the new partnership, 1Password customers will soon be receiving an email offering early access to Comet as well.
