We recommend using different usernames for different sites, within reason. We recommend using AnonAddy to create burner email addresses for websites that require email addresses instead of usernames. However, when you can choose a different username, we recommend using usernames for different types of online activity, such as for financial, healthcare, insurance, shopping, etc. Your password manager, such as Bitwarden, can help you remember your usernames to various sites.
Q. Do I need different usernames for every log in or can I just stick to using different passwords?
