Hello Guys!

I would like to know what's the best way(if there is any) to get a mnemonic (recovery phrase) from a private key.
I have an Eth address which I created using the client "MyEtherWallet". I have been able to handle transactions on this address but know I would like to import it into mist or a mobile client as Jaxx. Right now I have the private key and also the json file (Which I can download from Myetherwallet.com anytime)

So a mobile wallet as Jaxx (Android version) asks me the recovery phrase or mnemonic in order to pair my device to that address.

This is the main reason to ask you some guidelines about this.
If you could point me to a tutorial or give the guidelines I will appreciate it.

Thanks in advance for your time!

Tip me. DASH Xne9JXZhbL9u38xfr6aDtTGogZMZFBbpRN

Hi, I have the same problem.

With bitcore-mnemonic, the library generate the mnemonic for an extended private key.

According to
https://www.ethnews.com/jaxx-to-abandon-ethereum-hierarchical-deterministic-structure-and-embrace-more-erc20-tokens
I don't want to use an HDWallet for Ethereum.

So, is there a way to generate the mnemonic from a private key (not extended) ?

Of mnemonic phrases, you can retrieve the private key.
But from a private key, you can not get a mnemonic phrase. Sad

OK, since I start from scratch, I can generate the mnemonic and then the private key.
Is there a library for that ?

Yea, at the bottom of this page (a tool to generate mnemonics by Ian Coleman) you can find all libraries you need: BitcoinJS, jsBIP39.
