When you import passwords or other data (like bookmarks and history) from another browser, your operating system may show a prompt asking for access to its secure storage — Keychain Access on macOS or Credential Manager on Windows.
Browsers store passwords inside these protected system vaults, and your OS controls the handoff between them.
Granting access simply allows macOS or Windows to decrypt and transfer the passwords you selected to import.
Comet itself never sees or stores your vault directly — the transfer happens locally and securely through the system’s APIs.
If you deny the request:
Bookmarks and history will still import normally.
Passwords and saved logins won’t be transferred.
In short: this prompt isn’t from Comet — it’s from your OS, making sure only you authorize access to your encrypted credentials.
