Now that computer is lost long time ago, but I think I still know password and account name.

What does the "account name" looks like?
For safety and privacy, you can replace every character or a few, but do not change the format.

Or it is stored on device?

Those "not website" wallets usually stores the wallet file in the device itself.
But applications that require username and password usually has it in their server.

How can I get my coin back?

The beauty of Bitcoin is it's non-custodial, means that there's no custodial service or server who hodls your Bitcoins for you.
With it, no one can recover your bitcoins from a server, even the developers do not have access to anyone's bitcoins.
You need to recover the wallet file or any backup of it.

That's unless your login details are from an exchange, some custodial wallet, or web wallets.
In that case, it depends if the service or owner is still active.
