In a nutshell, no. You can check the elementary Privacy statement on the website, which says:
Your data always belongs to you, and only you. We don’t make advertising deals or collect sensitive personal data. We’re funded directly by our users paying what they want for elementary OS and apps on AppCenter. And that’s how it should be.
And specifically ...
This is a security feature according to an explanation from another Stack Exchange community. Here are the two vulnerabilities solved by that feature:
this (sic) throttles login attempts, meaning someone can't pound the system as fast as it can go trying to crack it (1M attempts a sec? idk).
If it did it as soon as it verified your credentials were ...
Using recovery mode:(using live usb/cd)
I assume you are the only user and the administrator of your system.
To change password, hold the shift key while booting live usb/cd. If that doesn't work, hold the shift key and hit esc key once after BIOS.
Note: Use arrow keys to navigate.
Select advanced options --> select recovery mode
Now using the arrow ...
The security standard Google is talking about is called OAuth. It's a modern technology to authenticate a user. As the Wikipedia article states:
Google supports OAuth 2.0 as the recommended authentication mechanism for all of its APIs.
Geary is using IMAP/POP3 authentication, not OAuth. That's the problem. elementary OS actually supports OAuth ...
What is sudo?
sudo is running the following command with super user (root) privileges. That's basically the "administrator" you might know from other platforms. But why is this dangerous? Because with super user privileges, everything can be done on your system (as it has access to all files and your system's whole functionality). Remove every ...
Ubuntu uses Unity as its desktop environment and this contains the code for Amazon Web Search and collecting data.
elementary OS has its own desktop environment called Pantheon which like most desktop environments remembers recently used files to enable extra functionality in certain applications while using the OS. This data isn't ...
Option 1: Manage with Seahorse
Typically, matching your keyring password to your login password will unlock your keyring at logon (unless the logon is automatic). You can install the management application seahorse to modify your keyring password to match.
sudo apt install seahorse
Option 2: Delete the Keyring
If you're not concerned about ...
The commands (pkexec and sudo -i) in and of themselves aren't necessarily harmful. However they do different things in terms of granting permissions to apps.
The sudo ("substitute user do") command allows you to run a process as another user, typically the root user. That is, by default it runs the process as a user with unlimited power.
When you use ...
"Doesn't meet modern security standards" is Google code talk for not an in-house developed application. By default, Google locks out most third party clients from IMAP access, but you can change that here:
Update: Should be fixed in the AppCenter 1.2 update, but try the following if it persists:
I haven't had this issue since I disabled the AppCenter from running in the background.
To kill AppCenter in your current session, run killall appcenter.
To disable AppCenter at startup, see Disable AppCenter dock reminder—there is a terminal way and a gnome-session-...
While Ubuntu is derived from Debian, Ubuntu has its own security team. This team is responsible for security updates to land in the Ubuntu software repositories.
As elementary OS uses the Ubuntu repositories, it's getting security updates from Ubuntu - While it's possible the Ubuntu security team adapts security updates from Debian, Debian security updates ...
As Daniel said, libpwquality is used. Looking in source code, you can see several checks, quality settings - threshholds - will be configured in a configuration file:
simplicity (too little number of digits, lower chars, upper chars and special chars)
simplicity (too little different character types - digits, lower chars, upper chars and ...
Use Gnome Encfs Manager. It's not an official elementary app, and it doesn't work from within Files, but it's worked really well for me. You can have the program launch at startup, or you can just summon it from slingshot whenever you need it. The interface displays a list of your encrypted stashes, so you don't have to hunt them down. I like that I can ...
Sudo is used to give a normal user the permissions as an administrateur. One of the bad things that might happen to you
Using a command to remove the whole / folder, for example sudo rm -rf /usr
Removing an important application/drivers that will make your desktop unusable, for example sudo apt-get remove wingpanel* slingshot*
How to reduce the danger
Are you running wine? If so, try clearing out your virtual C drive. If you have one, it's incredibly unlikely it's anything but a Windows virus hijacking a wine installation. Linux viruses are exceptionally rare and those that do exist typically target the larger server based distributions rather than smaller desktop distributions.
I would say more than ...
Install seahorse and seahorse-contracts.
sudo add-apt-repository ppa:elementary-os/daily
sudo apt-get install seahorse seahorse-contracts
I recommend you remove the daily repo after installation to avoid getting updates that may break your system.
sudo add-apt-repository --remove ppa:elementary-os/daily
There is no need for these changes to be made within Freya, as the update is being delivered via the update manager. You should upgrade there, or the correct way to upgrade to the Xenial Hardware Enablement Stack via the command line like this:
sudo apt install --install-recommends linux-generic-lts-xenial xserver-xorg-core-lts-xenial xserver-xorg-lts-...
I have a strong feeling that this question comes from confusion about what the URL scheme is.
The Preferences URL specification is only a way to open settings applications to the correct location. It is not a way to transmit any kind of data.
Settings URLs look like this:
This URL will only open the settings application ...
Get the CA which is missing. In my case:go to lets encrypt web site (or any other missing CA cert site). Copy the CA in PEM format (the format that has ----BEGIN CERTIFICATE---- in it) into /usr/local/share/ca-certificates and name it with a .crt file extension.
Then run sudo update-ca-certificates
You can verify if this worked by looking for the ...
Using live USB/CD : (using recovery mode)
Boot from live usb/cd and open terminal.
Use gparted or fdisk -l to identify elementary OS partition from the list.
The partition is just something like /dev/sda1
Mount this somewhere (Be sure to select correct partition)
sudo mount /dev/sda10 /mnt
. In my system elementary OS partiton is /dev/sda10, ...
To reduce the rate of login attempt
To prevent quick brute forcing of passwords.
This makes it take longer to guess passwords.
Greatly increase security
It's actually to prevent brute force attacks from trying millions of passwords per second. The idea is to limit how fast passwords can be checked and there are a number of ...
This question isn't totally fully answerable. Security is complicated and it largely depends on you, the user. Unsafe behavior, specifically you willingly giving away admin privileges, is the biggest vulnerability in any system. That said, some general kind of security advice:
Use a password and lock your session. If someone can walk up to your computer and ...
Primeiro, a password deve ser a de um utilizador root/administrador.
Segundo, a única forma de atualizar o Freya para o Loki é reinstalando o sistema. Alem disso, é impossível uma atualização completa para outra versão do elementaryOS ter só por volta de 300MB
First the password should be the one from a root/admin user.
Second the only way to upgrade from ...
You actually did install Firefox the safe way inside the OS. However, you used the command line instead of a graphical frontend. So no worries, there is nothing wrong with your Firefox installation, both alternatives have the same result.
Under elementary OS / Linux often "there is more than one way to do it…"
