My keys are random characters and I have a hard time remembering them. Unless you use one of these password managers

Do you have the same password for all your accounts or do you use a different? The truth is that the second is the best we can do in the event that some website has some vulnerability, but that can leave us with a problem: remember all passwords. In fact, it has happened to me, so it can be very useful to have a good Password manager. But … What is a password manager? A password manager is an independent program that is responsible for safely storing the passwords that we choose. In this way, once we register it, it will be saved and allow us to log in to the account without writing the password again. There are free services, but also other payment that offer a greater number of functions and, of course, of better advantages. In this article we will talk about Some of the best password managers, with their prices and differences. Proton Pass If we are going to choose a password manager, Better to do it by taking a discount, right? Proton Pass not only offers different monthly plans with its peculiarities, but also right now has a discount on all its subscription plans: Pass plus monthly by 4.99 euros a month instead of 4.99 euros. Annual Proton Plus by 2.99 euros a month instead of 12.99 euros. Pass Family by 4.99 euros per month instead of 6.99 euros. * Some price may have changed from the last review All of them have some similar tools, such as cloud storageextreme end encryption, the possibility of saving passwords or email encryption, calendar, cloud storage and VPN service. Here we leave you a table with some of the differences between the subscription plans: Pass plus monthly Annual Pass Pass Pass Family Tools Unlimited alias of Hide-My-Email Integrated 2FA authenticator Safe link exchange Unlimited credit cards Dark Web monitoring Advanced Accounts Protection Your personalized domain for alias Additional mailboxes for alias Unlimited alias of Hide-My-Email Integrated 2FA authenticator Safe link exchange Unlimited credit cards Dark Web monitoring Advanced Accounts Protection Your personalized domain for alias Additional mailboxes for alias 6 Pass Plus accounts Administrator panel for your family Price 4.99 euros / month 2.99 euros / month 4.99 euros / month Obviously, Proton Family offers greater users. Yes, it is more expensive, but it can be interesting if what we are looking for is to use the service on different devices. Pass Plus monthly can be interesting to prove the annual plus tools and Pass has the best value for money by staying the monthly for half that with respect to Pass Plus monthly. PUREVPN PUREVPNas its name indicates, it is mainly a service that offers a VPN tool, although it also has many other security related, such as the password manager. Taking into account that the standard service does not offer the password manager, we would have two modalities: Pure VPN Plus for $ 2.96 per month (2.52 euros to change), with VPN service and password manager. PUREVPN MAX for $ 3.33 per month (2.83 euros to change), with VPN service, password manager, Dark Web monitoring, unlimited ESIM data and data eliminator. * Some price may have changed from the last review Bitwarden Another option that can be interesting is Bitwardena password manager who, although it is true that it has a free modality, has two subscription modalities with more tools. Of course, it is more focused on companies than individuals, although that does not mean that it cannot be useful: The biggest difference between Bitwarden Teams and Bitwarden EnterpriseIn addition to the price, Enterprise offers a family plan and recovery administrator. Bitwarden Teams for 4 dollars a month (3.40 euros to change). Bitwarden Enterprise for $ 6 per month (5.10 euros to change). * Some price may have changed from the last review Dashlane Finally, Dashlane It is another service that, despite being more expensive, also offers a good assortment of tools. Mainly it is a password manager service, but depending on the subscription modality that we choose we can have more or less functions, although in this case they are more focused on companies: Password administrator by 8 euros per month (with annual billing). It includes access protection of employees with unlimited passwords and optimization of security controls. Omnix by 11 euros per month (with annual billing). Includes password administrator, intelligent alerts and additional protection against Phishing. * Some price may have changed from the last review Some of the links of this article are affiliated and can report a benefit to Xataka.

JPMorgan has managed to generate really random numbers. The questions are what he needs them for and how he has done it

A classic computer cannot generate Really random numbers. The algorithms used in computer science to produce this type of numbers resort to an initial value usually known as “seed”, so that making mathematical calculations with it is possible Generate one or several pseudo -elementary numbers. In this context it is necessary to use the ‘pseudo’ prefix because the need to resort to that initial value, to that seed, causes the numbers that we obtain Don’t be really random. In fact, when taking the seed we have several options. Some algorithms resort to the system clock, and it is even possible to increase the apparent randomness of the generated numbers sequence using entropy sourcessuch as the mouse movement or the temperature of the CPU in a certain moment. Even so, the numbers that we will obtain will not be really random because it is possible to predict them if we know the seed and the operations that have been carried out to generate them. Quantum computers, rescue For the gigantic American financial conglomerate JPMorgan the random numbers are very important. A priori may seem strange that a bank is interested in the procedures for generating this type of numbers, but, in reality, this capacity lies in the heart of their business. And it is that random numbers are fundamental in cryptography techniques Employees, for example, to transmit encrypted information, work with cryptocurrencies, develop gambling, and, in general, in any process in which it is necessary to have a randomly as possible randomness. To test their plan they executed their algorithm on a quantum computer of 56 cubits with ion traps manufactured by Quantinuum For this reason, in May 2023, several JPMorgan cryptographers wrote an algorithm of random generation generation that was designed to be executed in a quantum computer. Its strategy was to take advantage of the randomness inherent in the behavior of the cubits, whose functioning is governed by The rules of quantum physics, To generate bits whose randomness It could be proven afterwards. To test their plan they executed their algorithm on a quantum computer of 56 cubits with ion traps manufactured by the American company Quantinuum, which belongs to Honeywell. And it worked. They have detailed the result of their experiment in a very interesting article that they have published in Nature. To check if the numbers given by their quantum algorithm are really random JPMorgan researchers worked side by side with scientists from the National Argonne Laboratory, the National Laboratory OAK RIDGE and the University of Texas in Austin. In Your article develop the method they have used to Mathematically demonstrate using super -touches of the US Department of Energy that the numbers delivered by the quantum computer are genuinely random. “It is a revolutionary result (…) the next step requires understanding where we can apply this technology,” Asses Marco Pistoialeader of the project and head of applied research in Global Technology of JPMorgan.
