Maccy + 1Password / Bitwarden compatibility
Running a password manager alongside a clipboard manager should be safe, not risky. With Maccy it is: 1Password, Bitwarden, and Apple Passwords all play nicely, and copied credentials stay out of your history by default.
Why they are compatible out of the box
Good password managers flag copied credentials as concealed/transient on the macOS pasteboard. Maccy is built to respect that flag and skip those items. So the moment you copy a password from 1Password or Bitwarden, Maccy simply does not record it. There is nothing to enable.
Manager-by-manager
| Marks concealed? | Safe with Maccy? | |
|---|---|---|
| 1Password | Yes | Yes, automatically |
| Bitwarden | Yes | Yes, automatically |
| Apple Passwords | Yes | Yes, automatically |
| Most reputable managers | Usually | Yes |
If a manager does not mark concealed
A few smaller or older tools may not flag their copies. If you are unsure, test it: copy a password, open Maccy, and check whether it appears. If it does, add that app to Settings → Ignore so nothing from it is captured — see the ignored-apps guide. That closes the gap for any manager.
Autofill is even safer
Where possible, use your manager’s autofill or its keyboard shortcut to fill credentials directly, rather than copying at all. Nothing touches the clipboard, so there is nothing to capture or clear — the most secure path regardless of clipboard manager.
Peace of mind, verifiable
Because Maccy is open source, the concealed-item handling is auditable, not just asserted. If you want the deeper picture, read does Maccy see your passwords and the most secure clipboard manager overview.
How Maccy handles password manager clipboard writes
When you copy a password from 1Password or Bitwarden, that password is written to the macOS clipboard. Maccy monitors the clipboard constantly — but it does not record writes from password managers. Here is why, and how it works.
Two layers of protection
Layer 1: Default ignore list. Maccy ships with 1Password, Bitwarden, Dashlane, and macOS Keychain on its ignore list. Any clipboard write from these apps is silently ignored and never stored in history.
Layer 2: macOS secure clipboard flag. Password managers mark their clipboard writes with a “secure” flag in macOS. This signals to clipboard-monitoring apps that the content is sensitive. Maccy respects this flag regardless of whether the app is on the ignore list.
1Password specifically
1Password uses both the secure clipboard flag and has a built-in setting to clear the clipboard after a specified time (default: 90 seconds). When you copy a password from 1Password:
- The password goes to your clipboard
- Maccy sees it but ignores it (ignore list + secure flag)
- You paste the password in your target app
- 1Password clears the clipboard after 90 seconds
- Nothing was stored in Maccy history
Bitwarden specifically
Bitwarden on macOS also marks clipboard copies with the secure flag. Additionally, Bitwarden has a “Clear clipboard” option in Settings that clears the clipboard after a configurable time. Both mechanisms are respected by Maccy.
To verify: copy a password from Bitwarden, then open Maccy history. The password should not appear anywhere in the list.
Adding other sensitive apps to the ignore list
If you use a password manager not on Maccy’s default ignore list (NordPass, Keeper, Enpass, etc.), add it manually:
- Find the app’s bundle ID:
osascript -e 'id of app "AppName"' - Open Maccy Preferences → Ignore → click + → add the bundle ID
See the full ignore list guide.
Verifying no passwords are stored
- Copy a password from 1Password or Bitwarden
- Immediately open Maccy (⌘⇧C)
- Check the top item — it should be whatever you copied before the password, not the password itself
If the password appears in Maccy history, check that the password manager’s bundle ID is on the ignore list and that Maccy was restarted after adding it.
