Simplify your 1Password SDK integration workflows

Greetings, developers! ☃️

2025 is almost a wrap, and as I sit here trying to think of a clever em dash joke, it’s impossible not to notice how prevalent AI has become this year – especially in coding.

AI was undeniably the main character for developers in 2025. We witnessed our IDEs transform from offering basic autocompletion to becoming full-context collaborators. LLMs have never been so capable of complex operations, and we're now seeing meaningful AI participation in our code reviews, pipelines, analytics, logging, and even incident responses. AI is fundamentally changing how developers work. That’s why I'm so proud of the work 1Password’s developers have done to enable us all to use AI more safely and effectively.

This year has been a big milestone for developer tooling at 1Password, with major updates and products that help developers build and automate securely.

We kicked things off this year by retiring Vault Access Credits and unlocking unlimited Connect usage for all customers. Summer marked our launch of the beta version of Developer Environments, with support for AWS Secrets Manager and local .env file mounting. This was our first step toward making secure, simple secrets workflows accessible directly from the desktop, and paving the way for agentic development. We also launched early access to Agentic Autofill with Browserbase Director support, enabling more powerful, contextual autofill experiences.

More recently, we rolled out the public beta for desktop-based authentication with our SDKs (more on this below 👇), expanding the ways developers can authenticate and build locally through the 1Password desktop app.

Looking ahead at 2026, our focus is clear: as developers continue to evolve with a fast-moving AI ecosystem, 1Password intends to set the standard for secure, responsible access to sensitive data in AI-driven development.

Thanks for building with us this year, and we can’t wait to share what’s coming next!

Introducing: Authenticate 1Password SDK integrations through the desktop app

It just got a whole lot easier to work with 1Password SDK integrations locally. You can now set up your 1Password SDK integrations to authenticate using secure, local authorization prompts through the 1Password desktop app – whether it’s biometric unlock, a 1Password account password, or other supported methods.

This allows you to authorize SDK integrations the same way you unlock the 1Password app, making it faster and simpler to access your 1Password items while you’re coding.

Now available on macOS and Linux for SDK integrations in Go, JavaScript, and Python.

ICYMI: Local .env file support in 1Password environments

It’s official: developers have no excuse for storing their dev secrets in plaintext or sharing them in DMs. Dev teams can now store, organize, and manage their .env files in 1Password environments, allowing team members to collaborate securely and seamlessly in local development.

An Identity Security taxonomy for Agentic AI

Anyone working in software right now is hearing (and likely using) the phrase “agentic AI” a lot, but what does that refer to? Anand Srinivas, 1Password’s VP of Product and AI, breaks it down in this taxonomy for agentic AI, which can be used to help guide the specific security measures that must be considered for each agent.

Video: 1Password environments demo at DevTools Toronto

Last month, 1Password developer Sidharth Sudhir presented 1Password environments at the DevTools Toronto meet-up. His demo shows just how quick it is to add a new developer environment in 1Password and how to manage team permissions.

Open source contribution: Support reading .env from FIFOs (Unix)

At 1Password, we know secure software goes beyond our product codebases; it relies on open source contributions, too. Shoutout to Sidharth Sudhir for his accepted MR to add native FIFO (named pipe) support in python-dotenv – an addition that helps enable our .env file mounting.

How I finally started using 1Password as my SSH key vault by Khürt Williams

“The authentication step [before using the 1Password SSH agent] was always slightly annoying. Type the passphrase. Sometimes mistype it... Small friction, but constant. Now [with 1Password], it’s just a fingerprint. No typing. No remembering. No mistakes.”
We couldn’t have said it better ourselves. 😎
