Temporary email addresses are a type of disposable email address that are used to protect the privacy of a user. While these email addresses can often last as long as your regular email address, they are often set to expire in a predetermined amount of time.
Temporary email addresses can be set to last anywhere from a few minutes to several months depending on the provider. Usually, the provider will provide an option to choose how long the email address can be active. Typically, however, most providers will have a default expiry time of either one day, one week, one month or three months. Some providers may also offer the option of a customized expiry length.
While most temporary email addresses will expire on their own, sometimes users may have to manually delete the address to prevent it from being active for any longer than the specified expiry length. Once the temporary email address has been deleted, the user will no longer have access to messages that were sent to the address.
Overall, the duration of a temporary email address will depend on the provider. Some will have a set expiration date, while others may offer options to customize the duration. Nevertheless, it is important to keep in mind that once the temporary email address has expired, the user will lose access to any messages sent to the address.
