The use of your email as a personal identifier is a mistake, as it is often associated with a single identity, not just an access point, but also a central point of access to multiple services. Some services remove the need for a password, allowing users to register using their email and a one-time code sent to it. This is a misuse of this information as a tool for hackers to gain access to information about individuals and their identity. The use of an email as an identifier is also a mistake.
