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.
Krypton (https://krypt.co), now owned by Akamai (https://akamai.com/mfa) who removed one of the best features, IMO (SSH key on a phone...) does this to an extent... Akamai says it's FIDO2... have not used it in a while... It is free though until Akamai decides not to give it away...
