Short answer: no. A real police officer will never ask for your crypto recovery phrase, passwords or security codes. If a caller who says they are the police asks for any of these, it is a scam, even if the number looks genuine.
The phone rings and the caller says they are a police officer or detective. The story is usually the same: a suspect has been arrested, and they were carrying your passport, driving licence, bank details or other personal documents. Sometimes the caller says your crypto account has been linked to a crime, or that your wallet is at risk.
Then the questions turn to your money. Do you own cryptocurrency? Which platform do you use? Is it on a hardware wallet? Once they know, they push you to "secure" your funds. That might mean reading out your recovery phrase, sharing a security code, typing your phrase into a website they send you, or moving your crypto to a "safe" wallet that they control.
In some versions, a second person calls later, pretending to be from your crypto platform or wallet company, to make the story feel official. They may send you to a fake webpage that looks just like the real app.
In October 2026, Greater Manchester Police warned of a rise in calls from fraudsters pretending to be officers. The calls appeared to come from real police phone numbers, and the callers tried to get people's crypto account details, recovery phrases and security codes. In July 2026, New Zealand Police said scammers posing as detectives had taken millions of dollars from crypto holders using the same "we arrested someone with your documents" story. In North Wales, one person lost £2.1 million in Bitcoin after a fake senior officer sent them to a convincing fake website, where they typed in their seed phrase.
Your recovery phrase is the master key to your wallet. Anyone who has it can empty your wallet in seconds, from anywhere in the world, and crypto transfers are almost impossible to reverse.
The rule is simple: your recovery phrase is for you alone. Not the police, not your bank, not your crypto platform, and not anyone on the phone.
