Five myths about safer signup addresses

The five myths

• It makes you anonymous
• It stops every phishing message
• It removes the need for strong authentication
• Every address should be temporary
• More addresses always mean more confusion

What is actually true

Decide whether the account needs a durable alias before completing the form. That can reduce correlation, improve context and make one exposed relationship easier to replace. It is a control surface, not an invisibility cloak.

Why the distinction matters

You want a trial today but may need receipts or recovery next year. The address can tell you which relationship is involved, but it cannot certify the sender or erase information shared elsewhere.

Good tools solve a named problem. Myths ask them to solve every problem.

Use the modest superpower

Short-lived addresses are a poor fit for accounts you may need to recover.

• Check the recovery need
• Create a unique alias
• Use a unique password
• Record what the address is for
