Please explain Brainwallet

Dear Sirs,
I created a testnet brainwallet.
I gave the password “braintest”

I have a wlt file in my computer called
braintest.wlt

the question is:
how can I get access of this brain wallet from
another computer without having the wlt file?

Simple, you don’t need the wlt file to access the brainwallet. Wlt file is created locally just so nanowallet can interact with it.

thankyou than,
how can I see the brainwallet content?
Without using wlt file.

That is not an option with nanowallet
