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.
Also https://twofactorauth.org/ to check which of your sites have it as an option.
I recommend Bitwarden if you're doing this for yourself (https://bitwarden.com/). 1Password is the one I use and I think it's better, but it's also expensive. (https://1password.com/)
