Replacing a secret while others work
You do not replace a key at night when nobody works: it happens while colleagues run workflows and update connections. A new version applies from the next call, also in a workflow that is already running; a version you switch off is no longer used anywhere. The list of connections says which secret no longer works, and when a colleague works on the same connection at the same time, both their change and yours are kept. Below you see both people's screens side by side.
A new version of the key
Open Security → Secrets, choose the secret and click New version. Type the new key and save: from the next call every connection and workflow uses it, also a colleague's workflow that is already running.
Your colleague works on the same connection
Bob opens the web shop connection to give it a clearer name. Meanwhile you choose another secret for that connection. Bob saves: Flow does not overwrite your choice, but says what each of you changed. Review lists it.
