Echo Dot help needed please

[mckenzie]

When DS sets the alarm on his Echo Dot, it also activates the alarm on DD’s one.
We know that DS is very loud and assume that’s why it happens but is there a way to set DD’s one so that only her voice can activare it or these is a secrecy code to use to activate it?

TIA

Could he use the echos name when setting it, 'set alarm on ds echo at x time'?

Thank you very much
That seems to work.
