Troubleshooting

Login fails with "Incorrect password" → Enter your encryption password (for moneyflow), not your Monarch password → If forgotten: Click "Reset Credentials" or delete ~/.moneyflow/

2FA not working → Copy the BASE32 secret (long string), not the QR code → Get fresh secret: Disable and re-enable 2FA in Monarch Money

Terminal displays weird characters → Use a modern terminal with Unicode support (iTerm2, GNOME Terminal, Windows Terminal)

Complete reset

rm -rf ~/.moneyflow/
pip install --upgrade --force-reinstall moneyflow
moneyflow
