Six secrets, in git

Six secrets sitting in your config file, in git. Everyone with repo access — past and present — has all of them.

Frequently asked questions

Does moving secrets into Key Vault remove all secrets from your app?
Almost — most tutorials stop at "your secrets are in the vault" while a ClientId/ClientSecret still sits in config to open the vault itself, which is one master secret standing in for six. A managed identity removes that last credential too, so the count reaches zero.
What permission model should a Key Vault app use?
Azure RBAC with the Key Vault Secrets User role — read-only, secrets-only — rather than the older, coarser access-policy model. The app should never be able to write, delete, or list keys.

These are built for a phone

Every short is drawn at full portrait height, the shape a phone already is. Installed, it opens full-bleed with no address bar across the top — and the whole library reads offline.
