Crypto exchange Gemini said Wednesday that a phishing campaign led to the collection of some customer email addresses and partial phone numbers.

"Some Gemini customers have recently been the target of phishing campaigns that we believe are the result of an incident at a third-party vendor," the company said in a statement. 

No account information or systems were impacted, and all customer accounts remain secure, Gemini said. 

Gemini reminded clients that it did not recommend relying on the secrecy of an email address for strong authentication methods.
