Password strength requirements for Safe4 are being increased

Cyber crime, identity theft and online fraud are becoming more frequent. It is known that there are large organisations, some of whom are state-backed, whose sole purpose is to disrupt the lawful activities on which much of our normal economic life is based. Recent ransomware attacks, as well as the ever-increasing use of spam email, are evidence of the scale of the threat. For this reason, the password strength requirements for the Safe4 system are being increased.

Safe4 works very closely with a number of public-sector organisations for whom security is paramount. Acting on the advice of the UK National Cyber Security Centre, part of GCHQ, the password requirements for Safe4 are being changed to incorporate a minimum length of 10 characters and a maximum of 150 characters. As before, each password will have to contain an upper and lower case alpha character, a number, and a symbol such as a punctuation mark. Passwords will accommodate spaces as well as normal characters, thus allowing the use of pass-phrases as well as basic passwords. The advice of the NCSC is that passwords up to 8 characters can now be cracked by brute-force attack methods in a few minutes, whereas those with 10 or more characters are unlikely to be cracked in meaningful time.

Password strength matters

Choosing a new password is increasingly challenging, hence the ability to use a pass-phrase for Safe4. This can be a favourite piece of text, such as line from a book or song, which will generally be easier to remember than a shorter password containing an obtuse string of characters. The longer the password, the more difficult for criminals to crack it. A random sequence of words that are easily remembered will have the same effect.

An additional feature that Safe4 have incorporated in this release is a warning message if the password chosen by a user has already been compromised on another site. This does not prevent the selection of that password, but the user is warned of the potential risk.

Following the release of Safe4 version 6.01, scheduled for 25 May 2019, new users will be invited to create accounts using the updated password strength requirements. The new rules will also be applied to password changes and to resets.

2-Factor Authentication by Text Message

At present, the 2-factor authentication applied by Safe4 is based on the use of a 6-digit PIN as well as a username and password. In July 2019 this will be changed, and the PIN will be replaced by a numeric code sent to the user by text message.

We at Safe4 are constantly trying to ensure that the system is as secure as possible, and that our customers’ data is protected to the maximum extent.

Password strength checker improvements for Safe4

One of the challenges of enforcing strict rules about the strength of passwords is how to make them secure and still easily usable by people who perhaps utilise a system occasionally and often need rapid access to share or obtain important information.

Safe4 has now been updated to make it easier for users to select passwords in the first place, by listing each of the strength requirements and showing visually when these have been satisfied. Because Safe4 is used in many countries around the world and by speakers of many languages, it can be difficult to prevent users from choosing a password that is a common word in one language but not in another. Using sequential characters on a keyboard is also potentially an issue, as in several European countries different keyboard layouts are utilised. Beyond Europe, in countries where alphabets may also differ, keyboard layouts are often radically different from those familiar in Anglophone regions.

Keeping it simple without sacrificing security

Safe4 has become established as one of the most secure sites on the Internet, and consequently enforcing strict password requirements is essential given the presence of brute-force attack systems that can crack simple passwords very quickly. Whilst setting a strong password is the responsibility of each individual user, applying specific rules governing this, as well as limiting the number of unsuccessful login attempts within a single browser session, makes it easier to prevent unauthorised access to the system. The changes made by Safe4 will inform new users of the strength of their password as each character is chosen, and show any discrepancies visually.
