Refresh Loki password in macOS Keychain from 1Password	Bash(op read *, security add-generic-password *, security delete-generic-password *)

Refresh Loki Password

Re-fetch the Loki password from 1Password and update macOS Keychain. Use this when the password has changed or Keychain entry is missing.

Steps

1. Delete existing Keychain entry (if any)
2. Fetch password from 1Password via op read (Touch ID required)
3. Store in Keychain

security delete-generic-password -a "$USER" -s "some-service-loki-password" 2>/dev/null; \
PASSWORD=$(op read 'op://53tfffjfzb67nmifffyovg37m/tmqv4kffffffqjzlxgy3bume/devpl-0') && \
security add-generic-password -a "$USER" -s "some-service-loki-password" -w "$PASSWORD" -U && \
echo "Loki password refreshed in Keychain"
