#How to find mac os keychain password password
The keychain could be locked, or the password cannot be found. This command might fail for different reasons.
Once you have tested that you can retrieve the password in the interactive shell, and you have granted access to the security binary, you can use command substitution in the script to get the password: cli_password=$(security find-generic-password -w -s 'CLI Test' -a 'armin') This is more secure, but also requires more user interaction. Whether you grant access through the UI or with the command, keep in mind that a every other script that uses the security binary will also gain access to this password.įor very sensitive passwords, you can just click ‘Allow’ rather than ‘Always Allow.’ Then the script will prompt interactively for access every time. When you create the item with the security add-generic-password binary, you can add the -T /usr/bin/security option to immediately grant the security binary access. You can see this in the Keychain Access application in the ‘Access Control’ tab for the item. This will grant the /usr/bin/security binary access to this password. Enter your keychain password and click the ‘Always Allow’ button to approve the access. The first time you run this command, the system will prompt to allow access to this password. When it finds an item that matches the name and account it will print the password. This will search for an item in the keychain with a name of CLI Test and an account name of armin. > security find-generic-password -w -s 'CLI Test' -a 'armin' To retrieve a password from the keychain in a script, use the security command.

How to Retrieve the Password in the Script This will create an item in the Keychain with the name CLI Test and the account name armin and the horribly poor password password123. > security add-generic-password -s 'CLI Test' -a 'armin' -w 'password123' You can also add the password from the command line with the security command. The “Keychain Item Name” is what we are going to use later to retrieve the password, so watch that you are typing everything correctly. Then enter the Keychain Item Name, Account Name and the password into the fields. Open the Keychain Access application and choose “New Password Item…” from the Menu. Since adding the password to your keychain is a one-time task, you can create the password manually. Update: I didn’t remember this, but Graham Pugh has written about this before. Note: Mischa used this in his ‘OnAirScanner’ script. This approach has the added benefit, that you do not have to remember to remove or anonymize any keys or passwords when you upload a script to GitHub or a similar service. However, it is quite useful for workflow scripts that you run interactively on your Mac.
Since the user can go and inspect the key in the Keychain Access is also not well suited for critical passwords and keys.
the user and other scripts can find and read the password in the Keychain Access application or with the security toolīecause of these limitations, this approach is not useful for scripts that run without any user interaction, e.g.the keychain has to be unlocked when item is created and when the script runs-this usually requires the user to be logged in.the user has to approve access to the password at least once.the password item has to be created in the keychain.We can have our script retrieve a password from a local keychain. MacOS has a keychain, where the user can store passwords and allow applications and processes to retrieve them. You can even try to encrypt the password, but since the script needs to be able to decrypt the password, you are just adding a layer of complexity to the problem. You can obfuscate the password with base64, but that is easily reversible. You can pass the password as an argument to your script, but that is inconvenient and may still appear in clear text in the ps output or the shell history. It is easiest to store the password in clear text, but that is obviously a terrible solution from a security perspective.

MacAdmin scripts often require passwords, mostly for interactions with APIs.
