Temporary Email Frequently Asked Questions
This service offers you a temporary email address that you can use to receive email from people/sites/organizations to which you don't want to give your "real"/everyday/"personal" email address.
This type of service is usually used for registering on sites which you don't want to have your "real" email address. Most of the sites offer additional functionality if you register or require you to register in order to use their services at all. If you're an "internet person" you might end up registering on several sites each day. But if you value your privacy or you hate spam or you just want to be on the safe side you would most probably not want to give your "real" email address. The problem is that all these sites require that you provide a valid email address and they check this by sending you an email with a link on which you must click. By using a temporary emailsensei email address you can see that email and click that link so your account will be activated on the site on which you have just registered.
Even if you trust the site you're registering on it is usually a good idea not to use an email address that you actually use every day because you will probably end up receiving all kinds of email that technically don't qualify as spam but which will probably not have much value to you: newsletters, promotional offers, updates, reminders etc.
While this is the typical use for this kind of service you might find useful in any other situation when you want to provide a valid email address without providing your "real" email address.
It's really easy. And it's even easier if you have Firefox.
If you don't use Firefox or don't want to use the emailsensei Firefox extension all you have to do is go to emailsensei.com home page and you will already have a randomly generated temporary email address that you can use. You just have to copy that email address and paste it wherever you need it. Then you click the 'View inbox' button on emailsensei.com home page and you get to see all messages received by this email address during the last 24 hours.
If you have the emailsensei Firefox extension installed you just right click on any text input field and in the 'emailsensei' submenu click 'Insert temporary email address'. You can always check the email for your last used temporary email address via right click anywhere on page - emailsensei - Inbox for last used temporary email
I'm glad you asked this question :) There are quite a few reasons for which you should use our service and not anything else with a similar concept:
- Privacy - we don't know any of your real email addresses because you don't provide them to us for using this service
- Security - the minimum length imposed on email names makes it nearly impossible to guess an email address; the additional time limit of 24 hours makes it even harder for two email addresses to overlap
- It's really easy to use - and you have a Firefox extension for it too :)
- It's free
Security is relative so there is no short answer for this question. But security is and always will be a major concern for us.
The main security issue you should notice is that anyone knowing the temporary email that you used will have access to your emails received during the last 24 hours just as you will. But this is not as bad as it sounds because it is nearly impossible to guess to guess a string that is at least 16 characters long. This really acts like a password and I doubt that your password even combined with your username gives a string longer than 16 characters. Brute force attacks are difficult to perform because they must be carried over the internet which is very much slower than running locally and on the other hand we take our own precautions - such an attack won't remain unnoticed. Even if the attacker would be successfull he has a 24 hour constraint - even if he guessed your temporary email address he won't see the email older than 24 hours.
There is obviously one thing you should notice in order to be on the "secure" side: you should not use the same temporary email address twice. That's why it's called 'temporary' in the first place. Failing to do so is a major security threat: the people/sites/organizations you have given the temporary email address to will have that temporary email address and that means they will have full access to your emails. This is not a problem if you have used this email address only for them (because they already know what they send you :) but it becomes a problem if you use the same address a second time - so just don't do it
If you are still concerned about brute force attacks you must remember that the length of the email address can go up to 255 characters and you can use any combination of characters that are allowed in an email address
Current limitations are:
- minimum length of email name (email@example.com): 16 characters
