| .SYNOPSIS | |
| Assigns Data Collection Rules to Azure VMs and Azure Arc servers. | |
| .DESCRIPTION | |
| This script connects to Azure, retrieves all Windows Azure VMs and Azure Arc | |
| servers from specified subscriptions, and applies Data Collection Rules to | |
| them. It is intended to streamline the setup of monitoring across both Azure | |
| VM and Azure Arc environments by automating the association of DCRs. |
*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August
This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.
