thanks for the valuable information , this mean the seedphrase are weak and more likely to fail with brute force? so actual passphrase is recommended but really i do need it or it just optional military grade thing for wallet ?
i have second pin for blockchain wallet , any highly established online wallet that provide passphrase ?
i run my machine with linux distro . attacks are not common .
That's actually not what I meant. The seed phrase will be impossible to brute force regardless of the wallet you're using.
The passphrase I was referring to, is a "custom word" (optional) you can add to your seed and memorize, that way, even if someone finds your seed written down, the hacker will just find an empty wallet since he doesn't have access to the custom words you've added.
Unstoppable wallet should support passphrases as mentioned here:

i think Unstoppable wallet is recently developed ? is there secure open source desktop wallet + widely used + highly established . does not require to download entire blockchain and linux compatible ? simple interface and low fees
