How do I join the Phone Insider?

[Yuiiski]

Hello, I am apart of the preview but just downloaded the Phone Insider app and it says "Find a program" so I clicked that and now it is asking for Microsoft Domain account and password, what is that? And how do I do such thing?

And also is the Phone Insider app the only way to get Windows Phone 10 early or can I still use my Preview app?

As stated nobody apart from MS dev team members can log in now.
And the answer to ur other questions will be available only after the MS event of Jan 21st...

Okay thank you!

But what exactly is my Microsoft Domain account? That's my email right?

No you don't have a Msft domain account, only their employees do. There will expectedly be an update to the app any day after Jan 21, which will allow our Microsoft IDs to login too.
