# TOTPFIT
### Another 2FAuthenticator based on TOTP for Zepp Amazfit GTS 4 with Google Authenticator migration support
![alt text](docs/assets/image2.png)
### Features:
- Supports of ```otpauth://``` links with parameters "client", "issuer", "algorithm", "digits", "period", "offset"
- Supports of `otpauth://` links with parameters "client", "issuer", "algorithm", "digits", "period", "offset"
- Addition/Edition/Deletion of TOTPs from mobile app
- Support of Google Authenticator migration links formated: ```otpauth-migration://offline?data=...``` (At this stage with only 6 digits and only 30 seconds period)
- Support of Google Authenticator migration links formated: `otpauth-migration://offline?data=...` (At this stage with only 6 digits and only 30 seconds period)
