Installation and Setup
Microsoft's PowerBI is the platform of choice for dashboarding. PowerBI comes with a native connector for Snowflake.
Reset connection in PowerBI
If you made a mistake in PowerBI when setting up your credentials to Snowflake, you'll notice that it is near impossible to change your settings. PowerBI is known for this.
Keypair Authentication
Next to username/password, Snowflake also supports keypair (public/private key) authentication. This is typically used for Service Accounts, since it avoids the need to type in a password (and thus avoids MFA) for programmatic / scheduled access.
