Anyone asking for a recovery phrase
This one gets repeated so often that people stop hearing it. Repetition has not made it less true and the reasoning is worth having rather than the slogan.
Bucket: NEVER
No legitimate party has any use for your recovery phrase, seed words, private key or mnemonic. Not to verify you, not to fix a wallet, not to expedite anything. There is no honest use case, so there is no honest request.
Why there is no honest version
A recovery phrase is not a password and it is not an identifier. It is the wallet. Anything that holds it can spend everything in it, immediately and permanently, with no further step. Handing it over is not granting access, it is transferring ownership.
Verification never needs it because verification does not work that way. Proving you control a key is done by signing something with it, which reveals nothing. Anyone technical enough to need proof knows this, which means anyone asking for the phrase instead is not asking for proof.
Why it works anyway
Because it arrives at the worst moment. After a failed transaction, a locked account, a mistyped awazon market address, a deposit that has not landed. The person asking is offering an exit from a situation that already feels like a loss.
Panic narrows attention to the immediate obstacle. A request that would look absurd on a calm Tuesday looks like a procedure when you have been staring at a stuck balance for two hours.
The variations
- A recovery tool or validation page that wants the phrase pasted in.
- A support helper who needs to import your wallet to check it.
- A migration to a new wallet that needs the old seed.
- An airdrop, refund or compensation that requires verification of holdings.
- A wallet that shows a scary error and offers to restore from seed.
They differ in story and not in structure. Every one of them ends with the phrase leaving your possession, which is the only part that matters.
What people get wrong
They think a partial phrase is safer. Giving a few words is a common compromise and it is still bad, because it reduces the search for the rest to something a computer can do. The words are from a known list and the ordering constraints are known.
They also think typing it into a page is different from telling a person. It is worse. A page can take it silently, and you will not know until the balance moves.
Where the phrase should live
Written down, offline, somewhere only you can reach, and never entered into anything except the wallet software you installed yourself. That is the whole procedure. It is unglamorous and it is not improved by any tool that offers to manage it for you.
Storing it in a note on the same device as the wallet undoes most of the point. So does photographing it. Both feel like backups and both put the phrase in places that sync somewhere.
What would move this
Nothing. This is the one page on this site where the honest answer to what would change my mind is that no situation exists. That is a strong claim and it is warranted, because the phrase is the funds and no legitimate operation needs to be handed the funds to help you with them.
If a piece of software genuinely needs a seed to restore a wallet, that software is running on your machine and you obtained it yourself. That is not a request, it is you using a tool. The distinction is who initiated it.
