Setting up and migrating to Dashlane from another password manager is simple, and you’ll use a secret key to encrypt your passwords, much like BitWarden’s setup process. In practice, Dashlane is very similar to the others on this list. Dashlane offers a 30-day free trial, so you can test it out before committing.

Best for Bundled Services

You might know Nord better for its VPN service, but the company also offers a password manager, NordPass, and a pretty nice online storage system, NordLocker. A part of the appeal of NordPass comes in bundling it with the company’s other services for some compelling deals. As a password manager, NordPass offers everything you need. It uses a zero-knowledge setup in which all data is encrypted on your device before it’s uploaded to the company’s servers. Unlike most services here, NordPass uses XChaCha20 for encryption. It would require a deep dive into cryptography to get into the differences, but the short story is that it’s just as secure and maybe slightly faster than the AES-256 encryption used by other services.

There’s a personal information storage feature to keep your address, phone number, and other personal data safe and secure, but easy to access. NordPass also offers an emergency access feature, which allows you to grant another NordPass user emergency access to your vault. It works just like the same feature in 1Password, allowing trusted friends or family to access your account if you cannot.

Other nice features include support for two-factor authentication to sign in to your account, as well as security tools to evaluate the strength of your passwords and alert you if any of your data is compromised. Note that NordPass Premium is theoretically $3 a month, but there are always sales that bring that much lower.

The downside, and my one gripe about all Nord services, is that there is no monthly plan. As noted above, the best deal comes in combining NordPass, NordVPN, and NordLocker for a bundled deal. A free version of NordPass is available, but it’s restricted to only a single device.

Best DIY Options (Self-Hosted)

Want to retain more control over your data in the cloud? Sync your password vault yourself. The services below do not store any of your data on their servers. This means attackers have nothing to target. Instead of storing your passwords, these services use a local vault to store your data, and then you can sync that vault using a file-syncing service like Dropbox, NextCloud, or Edward Snowden’s recommended service, SpiderOak. There are two services to keep track of in this scenario, making it a little more complex. But if you’re already using a file-syncing file service, this can be a good option.

You can also properly host your own vault with network-attached storage or a local server.

Enpass does not store any data on its servers. Syncing is handled through third-party services. Enpass doesn’t do the syncing, but it does offer apps on every platform. That means once you have syncing set up, it works just like any other service. And you don’t have to worry about Enpass being hacked, because your data isn’t on its servers. Enpass supports syncing through Dropbox, Google Drive, OneDrive, iCloud, Box, Nextcloud, or any service using WebDAV. Alas, SpiderOak is not currently supported. You can also synchronize your data over a local WLAN or Wi-Fi network.

All of the features you expect in a password manager are here, including auto-generating passwords, breach-monitoring, biometric login (for devices that support it), auto-filling passwords, and options to store other types of data, like credit cards and identification data. There’s also a password audit feature to highlight any weak or duplicate passwords in your vault. One extra I particularly like is the ability to tag passwords for easier searching. Enpass also makes setting up the syncing through the service of your choice very easy. Enpass added support for passkeys, too.

“In the old days, it was more like a luxury project,” says Deo de Klerk, team lead for heating and cooling solutions at the Dutch energy firm Eneco. Today, his company’s clients increasingly ask for district cooling as well as district heating systems. Eneco has 33 heating and cooling projects under construction. In Rotterdam, Netherlands, one of the company’s installations helps to cool buildings, including apartment blocks, police offices, a theater and restaurants, using water from the River Meuse.

It’s not hard to see why cooling technologies are getting more popular. A few years ago, Nayral moved out of Paris. She remembers the heat waves. “My routine during the weekend was to go to the parks,” she says. Nayral would sit there well into the evening—reading Les Misérables, no less—waiting for her apartment to cool down. Recently, she has increasingly found herself spending time in shopping malls, where air-conditioning is plentiful, in order to make it through searing hot French summers. This year, unprecedented heat waves hit France and other countries in Europe.

The city of Paris is now desperate to help its denizens find cool refuges during spells of extreme heat. A key component of Parisian climate adaptation plans is the river-supplied cooling network, the pipes for which currently cover a distance of 100 kilometers, though this is due to expand to 245 km by 2042. While around 800 buildings are served by the network today, those in charge aim to supply 3,000 buildings by that future date.

Systems such as Paris’ do not pump river water around properties. Rather, a loop of pipework brings river water into facilities where it soaks up warmth from a separate, closed loop of water that connects to buildings. That heat transfer is possible thanks to devices called heat exchangers. When cooled water in the separate loop later arrives at buildings, more heat exchangers allow it to cool down fluid in pipes that feed air-conditioning devices in individual rooms. Essentially, heat from, say, a packed conference room or tourist-filled art gallery is gradually transferred—pipe by pipe—to a river or lake.

The efficiency of Paris’ system varies throughout the year, but even at the height of summer, when the Seine is warm, the coefficient of performance (COP)—how many kilowatt-hours of cooling energy you get for every kilowatt-hour of electricity consumed by the system—does not dip much below 4. In the winter, when offices, museums, and hospitals still require some air-conditioning, the COP can be as high as 15, much higher than conventional air-conditioning systems. “It is absolutely magnificent,” boasts Nayral.

But those summer temperatures are increasingly a concern. This summer, the Seine briefly exceeded 27 degrees Celsius (81 degrees Fahrenheit), says Nayral. How can that cool anything? The answer is chiller devices, which help to provide additional cooling for the water that circulates around buildings. Instead of blowing out hot air, those devices can expel their heat into the Seine via the river loop. The opportunity to keep doing this is narrowing, though—because Fraîcheur de Paris is not allowed to return water to the Seine at temperatures above 30 degrees Celsius, for environmental reasons. At present, that means the river can accommodate only a few additional degrees of heat on the hottest days. Future, stronger heat waves could evaporate more of that overhead.

Europe’s fastest supercomputer Jupiter is set to be inaugurated Friday in Germany with its operators hoping it can help the continent in everything from climate research to catching up in the artificial intelligence race.

Here is all you need to know about the system, which boasts the power of around one million smartphones.

What is the Jupiter supercomputer?

Based at Juelich Supercomputing Center in western Germany, it is Europe’s first “exascale” supercomputer—meaning it will be able to perform at least one quintillion (or one billion billion) calculations per second.

The United States already has three such computers, all operated by the Department of Energy.

Jupiter is housed in a center covering some 3,600 meters (38,000 square feet)—about half the size of a football pitch—containing racks of processors, and packed with about 24,000 Nvidia chips, which are favored by the AI industry.

Half the 500 million euros ($580 million) to develop and run the system over the next few years comes from the European Union and the rest from Germany.

Its vast computing power can be accessed by researchers across numerous fields as well as companies for purposes such as training AI models.

“Jupiter is a leap forward in the performance of computing in Europe,” Thomas Lippert, head of the Juelich center, told AFP, adding that it was 20 times more powerful than any other computer in Germany.

How can it help Europe in the AI race?

Lippert said Jupiter is the first supercomputer that could be considered internationally competitive for training AI models in Europe, which has lagged behind the US and China in the sector.

According to a Stanford University report released earlier this year, US-based institutions produced 40 “notable” AI models—meaning those regarded as particularly influential—in 2024, compared to 15 for China and just three for Europe.

“It is the biggest artificial intelligence machine in Europe,” Emmanuel Le Roux, head of advanced computing at Eviden, a subsidiary of French tech giant Atos, told AFP.

A consortium consisting of Eviden and German group ParTec built Jupiter.

Jose Maria Cela, senior researcher at the Barcelona Supercomputing Center, said the new system was “very significant” for efforts to train AI models in Europe.

“The larger the computer, the better the model that you develop with artificial intelligence,” he told AFP.

Large language models (LLMs) are trained on vast amounts of text and used in generative AI chatbots such as OpenAI’s ChatGPT and Google’s Gemini.

Nevertheless with Jupiter packed full of Nvidia chips, it is still heavily reliant on US tech.

The dominance of the US tech sector has become a source of growing concern as US-Europe relations have soured.

What else can the computer be used for?

Jupiter has a wide range of other potential uses beyond training AI models.

Researchers want to use it to create more detailed, long-term climate forecasts that they hope can more accurately predict the likelihood of extreme weather events such as heat waves.

Le Roux said that current models can simulate climate change over the next decade.

“With Jupiter, scientists believe they will be able to forecast up to at least 30 years, and in some models, perhaps even up to 100 years,” he added.

Others hope to simulate processes in the brain more realistically, research that could be useful in areas such as developing drugs to combat diseases like Alzheimer’s.

It can also be used for research related to the energy transition, for instance by simulating air flows around wind turbines to optimize their design.

Does Jupiter consume a lot of energy?

Yes, Jupiter will require on average around 11 megawatts of power, according to estimates—equivalent to the energy used to power thousands of homes or a small industrial plant.

But its operators insist that Jupiter is the most energy-efficient among the fastest computer systems in the world.

It uses the latest, most energy-efficient hardware, has water-cooling systems and the waste heat that it generates will be used to heat nearby buildings, according to the Juelich center.
