3. If MFA is already enabled: disable and re-enable to get a new secret
4. When shown the QR code: click "Can't scan? View setup key"
5. Copy the secret key (base32 string like JBSWY3DPEHPK3PXP)
6. Complete MFA setup in Monarch Money with an authenticator app
7. Set the secret: export MONARCH_MFA_SECRET="YOUR_SECRET"
