InfluxDB
Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
Of course, 2FA is also a must. I'd highly recommend Aegis for this if you're on Android (otherwise Raivo OTP for iOS), which is also free, open source and better, more secure and more feature rich than Google Authenticator.
I'd highly recommend using a password manager like Bitwarden which is the best one along with 1Password. Unlike the latter, however, it's completely free and open source.
