How to use the credentials stored in the keyring/credential manager?

[kapitainsky]

You can pass your password in KOPIA_PASSWORD env variable or flag -p, --password=PASSWORD, so you can use your OS specific password manager software to retrieve password and connect to your repo.

PASSWORD = $(retrieve_password_from_keychain)
kopia repository connect ...--password=$PASSWORD...

Here some info how to do this in macOS:

Automating backups on macOS without the UI

I’ve had a great experience using Kopia and Backblaze to back up my Mac. I don’t use the Kopia UI, which makes automating the backups a little tricky, so I wrote up some notes to future me on how to set it all up, and figured I’d post them here as well in case they’re useful for anyone else.

For other systems you have to check documentation how to work with your specific key chain/password manager.
