Let's say, I have lost my mobile and I haven't stored a PIN of my Wallet then how could I recover my wallet? And isn't an easy option to fetch my Keys and withdraw my crypto?
Just like any other wallets, they don't use "pin" to recover the wallet, they use a seed phrase or private Key which you are supposed to back up before even ending any money to the wallet. If you lose the seed phrase or private Key, the mistake is all on you not them.
