@Dayt if you are looking for standard wallet in Metamask then simply enter empty passphrase when asked for i (click green button without entering anything)
Every case is specific, as users have different passphrases, or they are not using passphrase-protected wallets at all. If your coins are in a passphrase (hidden wallet), then you have to type in the exact same passphrase that you’ve once created for them. On the other hand, if your funds are not in a hidden wallet though you are prompted to type in a passphrase, leave the prompt window blank and it will help you get to your funds.
