Recovering wallet with passphrase from different vendor

[Petosiris]

Hi @Shiva1971,

I don’t know about Ellipal myself, but the standards Trezor support are mentioned in the first post here:

What would happen to my coins if SatoshiLabs (Trezor Company) went out of business?

There are no such plans because we are here to support the community and advance the use of Bitcoin. In the unlikely event that we had to close down, users would have nothing to worry about. Trezor wallets are fully compatible with other BIP32, BIP39 and BIP44 compatible wallets. These are open standards which anyone can use to recover their coins as long as documentation exists. Since our code is open-source and publicly available, developers from around the world can maintain it and add new …

So you should investigate what type of standard Ellipal uses. BIP39 is the most widely used standard, I think.
