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.
The standard unix password manager or pass is usually my go-to for things like that. There might be other ways to encrypt and decrypt files using GPG too.
The company has formerly used CyberArk (enterprise stuff) and by now migrated to 1Password, which is also available for private users and (comparatively) cheap (about 35 US$/year). [An alternative would be Bitwarden, and of course the ubiquitous KeePass port on your platform, both of which I haven't used extensively enough to wager an opinion.]
