People with 86 million dollars generally don't need to ask this.
People who have been tricked by con-artists are the sort of people that usually ask this.
That looks like a &quot;blockchain&quot; wallet.


How to unlock private key of bitcoin

I  need help on how to get the private key

You can follow the guidance on blockchain.com's support web-pages
Exporting the private key. The example given is for Ethereum but you should choose &quot;Bitcoin&quot; instead.
If your wallet doesn't have a private key for the bitcoin-address holding those 86 million dollars worth of Bitcoin, it means you have a watch-only address imported into your wallet.
If someone tells you that you need to pay them to release the private-key, it means they are a con-artist tricking you into giving them more money.

Backups
If you were not tricked but didn't make a backup of your wallet and a written backup of your password, private key or a written backup of your recovery phrase, and have lost or forgotten them -- you have been very negligent.
Recovery may be very very difficult, time-consuming, expensive, or quite likely, impossible.
Scams by con-artists
If an online friend/miner/consultant set this up for you, it means you are the victim of a scam.
If so, it is quite possible that the money you are looking at is money in the wallet of some innocent third-party whose bitcoin-address has been imported by a scammer into your wallet as a &quot;watch-only&quot; address. In which case it was never your money and any money you sent to the scammer was pocketed by them completely separately.
