Frequently Asked Questions

What Is This ?

This is a free tool provided by Llewellyns Accountants that allows you to check email addresses against all known recent large scale data breaches. This check will scan all databases and give you a full breakdown of where your email address appears in publicly released data breaches.

Is It Safe ?

Yes. We are only taking the email address entered and comparing it against a list of known publicly released data that has come directly from known large scale data breaches. We do not compare anything other than the data you enter here. None of your personal data is collected for this process. We do not keep a record of the email address used.

What Is A Data Breach?

A breach is an incident where privately stored data has been exposed due to a vulnerable system. For example, In October 2013, 153 million Adobe accounts were breached with each containing an internal ID, username, email, encrypted password and a password hint in plain text. This data is now publicly available.

The test shows I'm listed in a data breach, now what?

If this test shows you are included within a data breach that means that security information you have provided alongside the give email address is now public data. At some point (read the provided result for more info) your public data was stolen or leaked. Your email address and possibly other details including personal data and passwords are available to the public. The best thing to do is immediately change all passwords to something new and unique. Our results will show the date of each data breach, so if your latest password is more recent there is a strong chance you are safe, however more data breaches are being discovered as time progresses.

Our recommendation is to always, where possible, use 2 factor authentication (for example, a security code sent via SMS to your mobile). If a website doesn’t offer this service, then constant rotation of new and varied passwords is the best answer, despite it being somewhat annoying. It’s a small price to pay for data security.

The test came back with no results.. am I in the clear?

It would appear so, although some data breaches take years before they are made public. There is always the possibility of your data being included in a new hacking attempt or data breach. Changing passwords always provide a boost to security, but we recommend always using 2 factor authentication services where they are provided for maximum security.

What Is 2 Factor Authentication?

Many online services now require two forms of identification before allowing access to your account from new devices. For example, as well as needing a password you may also be asked to provide an access code sent to a mobile phone by SMS. This second check greatly increases security, as although someone may have your password, they are unlikely to also have access to your SMS messages. This is 2 factor authentication.
