In essence, the mnemonic seed is very important when we live on crypto.
Even more important than any advance security anyone can come up with as far our crypto asset is involved.
So, at this point, I have to make it clear because not only scammer, whoever it is: Authentic Customer support, real developer, or anyone with a genuine label, when asked your mnemonic seed, never give it!.
If truly there are Authentic Customer Support or even real developers. No one with clear intent will demand for mnemonic seed if not scammers. They can disguise and take up any identity just to lure their victims into falling prey to their mischievous tactics. It is really wild out there.
The only person who can access your wallet is you!. It's no longer important if you have bought an expensive hardware wallet, 2fa tool, or generated a difficult password when the Word Mnemonic seed was sent to anyone other than you. They are able to open that door even if it has been locked with maximum security.
2FA tool is only limited to our device, I stand to be corrected. The password is even as useless as anyone who will lose their mnemonic so cheaply to this scammers. It just like a bank or any financial institution giving out their customers details to random persons. I mean it will sound so absurd.
