Is it possible to disable MFA for couple of minutes if I'm not account admin?
If yes ... which privileges do I need to grant to specific user/role in order to get the rights to disable MFA for couple of minutes?
ALTER USER xxx SET MINS_TO_BYPASS_MFA = 10
Yes you need a role that is the owner of the user.
See how to grant ownership: https://docs.snowflake.net/manuals/sql-reference/sql/grant-ownership.html
Privileges for reference are listed here: https://docs.snowflake.net/manuals/user-guide/security-access-control-privileges.html#user-and-role-privileges
