Other Secure Apps You Can Use If You Want To Delete Or Stop Using WhatsApp.
~6.1 mins read

Since it was founded in 2009, WhatsApp has become one of the apps you’re most likely to find on phones worldwide. 

Today, it has over 2 billion users in 180 countries – even more than users of its stablemate, Facebook Messenger, which is presumably why Mark Zuckerberg’s company were so keen to gobble it up for an eye-watering $19 billion in 2014.

A new privacy policy revealed in January 2021 has meant the app requires you to share certain personal details with Facebook to continue using the app.

To use WhatsApp past February 8, 2021, you'll need to agree to the new terms that allow Facebook to see data including your phone number, status messages, profile names, IP address and more.

Many are looking to switch to an alternative app to ensure they don't have to share this data with Facebook, and that's where this list comes in. Below we've listed a variety of the top alternatives you can switch to as an alternative to WhatsApp.


Telegram is perhaps WhatsApp’s closest competitor in terms of functionality - and it even looks almost identical to the Facebook-owned behemoth. 

What sets it apart is that it doubles down on the promises over security: not only are messages end-to-end encrypted, but it is possible to set messages to self-destruct after a given period of time – leaving no trace of whatever important conversations you were having.

One other nice feature is that, unlike WhatsApp, it's truly multi-platform – with apps available for desktop, as well as mobile and on the web.


Many of these alternatives boast about their security credentials but if you’re really paranoid there’s only one option. Signal offers a similar suite of features to its competitors, as well as end-to-end encryption, but there’s one big difference: The app itself is open-source.

This means that all of the code for the app is publicly available to view, making it impossible for the creators to sneak in any backdoors that could give governments or hackers access to your messages. 

The app has also scored a major endorsement to bolster its privacy credentials even further in the form of NSA whistleblower Edward Snowden.


In response to the growth of WhatsApp, Apple has built out its own Messages app - iMessage - to be just as fully featured. Now, when messaging iPhone to iPhone, there are no character limits, you can send pictures, videos and… well, pretty much anything, thanks to a plethora of app integrations. 

Most notably, this includes Apple Pay in some countries, so that you can literally send money over text and, of course, Animojis. Hit a button and rather than type out your missive, you can perform it as a 3D animal puppet, with the fox, monkey or unicorn’s mouth movements matching your own. 

And yes, you can also be a talking poop emoji, but we recommend only using that when, say, dumping someone or telling a loved one about a death in the family.

There’s just one catch: iMessage is, by design, only available on Apple devices, so if you want to chat with your Android mates you’ve got to go back to using plain old 140-character SMS.

Google Messages

In response to Apple not playing nicely with iMessage, Google launched its own Android-only messaging service called…Messages. 

Available on the Play Store, this app also replaces your standard SMS app, and the big point in its favor is that it deeply integrates with all of Google’s apps and services. 

This means that you can easily share images from your Google Photos, or use Google Assistant to make a restaurant reservation with a friend from right within the app.

Facebook Messenger

This won't avoid the issue of sharing your data with Facebook, but it does pose a suitable alternative to WhatsApp for some. Facebook Messenger is an integral part of the Facebook experience, but a separate app enables private messaging between individuals and groups.

You may find this is more suitable for you than WhatsApp, especially as it works seperately from a phone number so you can use it across multiple devices at once without having to reauthorize the app.

Line, Viber, WeChat and others

There are a number of other messaging apps out there which have millions of users. Line, for instance, reportedly had 700m registered users in 2019 and Viber supposedly had 260m active users every month then too.

Some of these apps have some really interesting functionality too – for example, WeChat has an entire mini-app eco-system inside of the app, so that you can shop, order taxis and so on without leaving WeChat itself.

But we wouldn’t necessarily recommend making the switch to these apps as they may not be all that useful. Why? Because they’re mere minnows in the English-speaking world. 

WeChat dominates China, Line is the go-to messenger in Japan, and BlackBerry Messenger is the biggest in Indonesia (no, really) – which are great if you live there. If you’re in the UK, the United States, or Australia however, you’re not going to find that many of your friends on these apps.

Here's Why The Federal Government Wants To Block Your Phone Number Because Of NIN [Pulse Explainer]

Your phone number could be blocked before Christmas for security reasons.

On Tuesday, December 15, 2020, the President Buhari-led federal government, through the Nigerian Communications Commission (NCC), announced that mobile phone subscribers who are yet to link their phone numbers or SIMS to their National Identification Numbers (NIN) will have their lines blocked.
In a press statement signed by Dr. Ikechukwu Adinde, who is the Director, Public Affairs of the NCC, the commission said:
Telcos or network providers are required to get all their subscribers to provide valid NIN in order to update SIM registration records.

The submission of NIN by subscribers will take place within two weeks (from December 16 to December 30, 2020).

After the deadline, all SIMs without NINs will be blocked from the networks.

A ministerial task force, comprising the minister and all the CEOs (among others) will monitor compliance by all networks.

Violations of this directive will be met with stiff sanctions, including the possibility of withdrawal of operating license of the telcos.

In other words, the federal government is saying if you don't have a NIN, and if that NIN isn’t linked to your phone number between now and the end of the year, your phone line will be unable to make/receive calls or be used for internet purposes.

This directive is coming as Nigerians battle the coronavirus pandemic like the rest of the world.

A mad dash to National Identity Management Commission (NIMC) offices by Nigerians in a hurry to beat the government’s two-week deadline, could see Nigeria’s COVID-19 infections climb even higher, amid warnings of a second wave of the pandemic.
Exactly what a thinking government should be trying to avoid.

Why is the government doing this now?
The Senior Special Assistant on New Media to President Muhammadu Buhari, Bashir Ahmad, says this is being done for security purposes.
Government believes that harmonising all phone numbers through the NIN will help curb rising cases of terrorism and banditry because most of the bad guys would have no option but to link their phone lines to the NIN or lose their numbers.

“This will definitely help to curtail and checkmate the lingering security challenges in some parts of the country,”says Ahmad.

Even though NIN registration has been continuous and has been on for years, most Nigerians say there hasn't been enough awareness and a mass sensitisation drive concerning how the process works.

There have also been complaints that getting an NIN at the registration centers has been typically tortuous, frustrating and lethargic.

Imposing a deadline at Christmas
Imposing a two-week deadline for a process that is typically slow and tortuous at best, doesn't make plenty of sense either, especially because this is also holiday season in Nigeria.

Who wants to be running helter-skelter to register a phone number when you should be making merry with your family or traveling to make family thanksgiving?

The federal government has also been on a data harvesting spree for years, with not enough harmonisation of these plethora of data from agencies and organisations, into a single, reliable data base.

Since 2020, Nigerians have submitted biometric data information to the FRSC (Federal Road Safety Commission), mobile phone companies, the immigration service, the passport office, the electoral commission, to banks through the Bank Verification Number (BVN) and on and on it has gone.
That an NIN is still needed to harmonise biometric data for security purposes in Africa’s largest economy, speaks to the failure of government and the haphazard nature of government operations, analysts have submitted.

Gbenga Sesan, Director, Paradigm Initiative Executive Director


“This is a dumb move. It will be challenged,”says Gbenga Sesan, who is the Executive Director of Paradigm Initiative. "In July 2020, Nigeria had 198.9 million active lines. Guesstimate: 66.3million unique subscribers.
“By October 2020, 42 million Nigerians had been issued NINs. Even if NIMC increased enrollment from 500,000 to 2.5 million per month, current numbers will be 47 million NINs.

"Two weeks deadline? Make it make sense.”

Google And Mozilla Are Ready For Chrome And Firefox Version 100 To Break Some Websites
~1.6 mins read
Chrome, Firefox, and Edge are about to hit version 100, in a triple release that could break some websites. The move to version 100 in the coming weeks could result in bugs or compatibility issues on some websites not ready to read triple-digit user-agent strings. Google, Mozilla, and Microsoft are busy trying preempt any big issues.
Mozilla, Google, and Microsoft have been warning about the upcoming version 100 release for months, which is about to drop in March for both Chrome and Edge, followed by Firefox in May. Mozilla and Google have both been running experiments to test websites and report breakages. There’s a running list of issues, which is fairly small right now, and Engadget notes that the notable sites affected include HBO Go, Bethesda, and Yahoo.
“When browsers first reached version 10 a little over 12 years ago, many issues were discovered with User-Agent parsing libraries as the major version number went from one digit to two,” explains a team of web developers in a Mozilla blog. Much like the infamous Y2K bug that made the year 2000 indistinguishable from 1900 for some computers, browsers have different formats for user-agent strings, and “it’s possible that some parsing libraries may have hard-coded assumptions or bugs that don’t take into account three-digit major version numbers.”

While there are concerns around some websites breaking, a lot of hard work has been going on behind the scenes — much like what happened to avoid major headaches with the Y2K bug 22 years ago — to make the transition to version 100 go smoothly. Developers can enable a special flag in current versions of Chrome, Edge, and Firefox to make the browsers report as version 100 and aid in testing sites.

There are also plans in place if there are widespread issues. Mozilla says it will either hot fix broken websites or temporarily freeze Firefox’s major version at 99 if breakages are widespread and unmanageable. Google’s backup plan is to use a flag to freeze the major version at 99, and Microsoft hasn’t detailed a backup plan as far as we can tell.
