Images are taking too long to upload

If images are uploading slowly, it may be happening due to image size or slow internet connection.
Images bigger than 1MB should be compressed for faster uploading and also for higher speed of the web. For good overal results, try to keep image size under 500kB.
The image compression can be made online for free using https://tinyjpg.com/. This online tool has a limit for image size at 5MB. If the image is bigger than this, it is most likely also big in pixel size.
In this case, initially resize the image at http://resizeimage.net/ to comfortably fit the majority of computer screens (max. 2880 x 1800px) and then do the compression.

What is Two-Factor Authentication?

Two-Factor Authentication (2FA) is a one-time password (OTP) providing higher level of security.

Nowadays, more than anytime in the past, it's crucial to maintain security of data and information, but in the same time, to keep them accessible (even remotely) only to authorised users.
In most companies, user access information are just their username and password. In contrary to standard approach, 2FA complements the user's username and password with one more level of security.
The advantage is, that the user does not have to remember the authorisation code, as it is automatically generated by an application in mobile phone (e.g. Google Authenticator). Each code is unique, valid for a short period of time and completely random, thus not guessable.
The result of using 2FA is much higher level of security of company sensitive data against various kinds of cyber attacks.

OTP thus solves following issues:

  • using static passwords.
  • repeating password already used elsewhere.
  • passwords containing user specific data (name, surname, date of birth, ...).
  • passwords derivatives like 'my_secret_password_1', 'new-password-2', ...
  • using weak password (use at least 8 alphanumeric characters)

As a responsible provider of complex services, with regards to the upcoming legislation data privacy change* (25.5.2018), we support this improvement and strongly recommend it. Nowadays, Nux s.r.o. is able to to take care of this feature at professional level. We do even have a personal interest on the customer data security since the data are very fragile and vulnerable and prone to misuse.

Have you read this far and come to decision, that your data deserve this sort of increased protection and activation of the 2FA OTP service? Do require 2FA activation as soon as possible. For a one-time payment, we will immediatelly arrange 2FA for you. For those of you, who have service contract, all additional expenses connected to 2FA will become part of the contract after the activation.
