What is 1Password?
1Password is a security and privacy app for Mac that helps people store passwords, passkeys, payment cards, secure notes, documents, and other sensitive information in one place. It is designed for individuals, families, and teams who want an easier way to sign in to websites and apps without reusing weak passwords. The Mac app can generate strong passwords, organize items into vaults, and autofill credentials in browsers and supported apps. It also supports secure sharing, account monitoring features such as Watchtower alerts, and multiple unlock options including Touch ID on supported Macs. Published by AgileBits Inc., 1Password is commonly used across personal and work devices as part of a broader account security workflow.

Safety overview
Status: Safe
1Password is legitimate security software, but it is built to handle highly sensitive information, so the practical risk is tied to what you store in it. Access to browser integration, autofill features, biometrics, and local files is normal for a password manager. If you use it, protect your account with a strong account password, keep your recovery details available in a safe place, and be careful when granting browser or app autofill access on shared Macs.
Recommendation: Keep 1Password if you use it to manage passwords, passkeys, or secure information on your Mac. Remove it only if you no longer use the service and have confirmed you can still access any saved accounts, documents, or recovery information elsewhere.
