Use a distinct password for each account and never share a one-time code with a person claiming to provide support.
Password reuse
A reused password can expose multiple accounts when one service is compromised. A password manager can help maintain unique credentials.
Codes and unsolicited requests
A code may authorize a login or sensitive change. Read its accompanying message carefully. This publication will never ask for a password, OTP, payment information or identity document.
Privacy choices
Limit optional personal data, review account privacy controls and examine retention and deletion policies. A policy is a claim about practice, not independent proof of it.
