Error Handling

Error	Solution
"Not logged in"	Run `monarch-money auth login`
"MFA code required"	Set `MONARCH_MFA_SECRET` environment variable
"Invalid credentials"	Verify email/password work at app.monarchmoney.com

Session Management

Sessions are cached locally at ~/.mm/session.json. After initial login, subsequent commands reuse the saved session for faster execution.
