Sixty-five percent of organizations have already had an AI agent security incident, and most of them never told anyone. That's not a statistic. It's a warning. Your computer use agent is logging in, copying passwords, and saving tokens in plain text. You just don't know it yet.
The Credential Crisis Is Real
GitGuardian's State of Secrets Sprawl report found 29 million new hardcoded secrets leaked in 2025, and AI coding agents are one of the primary vectors. Developers copy production credentials into prompts to get things working. Agents echo those secrets into code commits, pull requests, and public repositories. One exposed OpenAI API key can cost you thousands in unexpected charges. A leaked database password gives attackers full access to your data. AI agents make credential handling harder, not easier, because they operate in environments where secrets were never meant to live.
Why Computer Use Agents Are Even Worse
- Computer use agents control real desktops, browsers, and terminals. They can click buttons, fill forms, and type commands just like a human.
- Most computer use tools don't have sandboxing or isolation. If an agent runs on your machine, it has access to your entire environment.
- AI agents can be tricked into revealing credentials through prompt injection attacks. A malicious website or chat message can make an agent log in to the wrong account.
- Companies using Anthropic Computer Use, OpenAI Operator, or similar tools are rolling these risks out to internal employees without proper controls.
The hardest problem with computer use isn't getting the agent to complete a task. It's keeping the agent from doing something stupid with your credentials. That's why most computer use agents are garbage in production.
How Companies Are Failing (Badly)
Enterprise automation vendors like UiPath do offer credential stores and rotation, but they're built for traditional bots, not agentic AI. They don't solve prompt injection, sandboxing, or the new attack surface created by computer use agents. Microsoft's Copilot Studio computer use does introduce secure Cloud PC environments, but that's only one vendor's solution in a fragmented market. Security teams are still guessing about what their agents are doing, where they store secrets, and whether they're vulnerable to attacks. You can't secure what you don't understand.
Why Coasty Exists (And Why It Matters for Credentials)
Coasty.ai is the #1 computer use agent because it actually understands the environment it's working in. Our in-house model scored 85.6% on OSWorld with public results and 82.81% on the official OSWorld-Verified leaderboard, higher than every competitor. That's performance in real tasks, not synthetic benchmarks. Coasty supports BYOK, letting you manage your own keys and secrets instead of trusting a vendor's infrastructure. It runs on desktop apps, cloud VMs, and even agent swarms for parallel execution. You keep control of credentials, Coasty handles the work. That's how you build computer use automation that doesn't become a security nightmare.
AI agent credential handling will make or break your automation strategy. If you're trusting random agents with your passwords, you're already in trouble. Coasty gives you a computer use agent that's fast, capable, and designed to keep your secrets safe. Sign up for the free tier, bring your own keys, and see why everyone else moved to Coasty. The alternative is waking up to a 29 million secret leak and wondering how it happened. Don't be that company.
