macos – How can I get administrator access to a Mac without knowing the current password?

I am sorry to hear about your father.

It is possible to reset the administrator password on a Mac quite easily, provided that you have the proper installation disk, corresponding to the version of the software running on the computer. Resetting the password does not delete any information on the Mac, but prevents you from accessing other system-saved passwords for items such as email accounts or wifi keys previously. entered and saved by the original user. .
Once you have changed the password, you will be prompted to create a new keychain, which is the name of the location where these other passwords are saved.

Once you have administrator access, you can create or delete accounts.
On the Apple website, you will find a support article on how to reset the password at the following address:

If you do not have the installation disc or if you need additional help, I suggest you make an appointment at the Genius Bar at your local Apple Store. They will help you reset it at no cost.

web application – Keep passwords in plain text in the "value" attribute. The addons can use it for password leaks

Either there is a security breach or I am missing information about something.

While I was testing the operation of the Surfingkeys addon, I noticed he had the command yf copy the form content to the current web page. I was thinking of trying it on the "Sign In" and "Sign In" forms on a few websites to see if it would be able to recover passwords typed in plain text. It was successful if standardized

the tags were used.

Then I noticed that in most web applications, the password is kept. plain text attribute that seems to me to be a standard security flaw for the entire W3 stack (HTML, CSS, JS, etc.). If this addon could get a DOM password, any addon can do it. The only thing missing is sending this data to the server of a third party that has such a malicious addon – such a situation had already occurred with Stylish.

The attack scenario looks like this:

  1. The company "mal1c1ous" buys a popular Web addon.

  2. They add to the generic addon

    analysis script that retrieves the data from .

  3. For each known website, they create their "Decorate" button with script buttons that, at the first click, send a request with credentials to their server and then to the host of that website. . Or, they simply send queries whenever the analysis script makes it possible to obtain new data.

  4. After a while, they launch an attack using the collected credentials.

I find that this possible scenario shows me that this can not happen. In addition, my question is this: Since web security is defective in design? Why is both visible to the user and accessible for plain text addons?

The thing is that no one discourages to use as a password holder, it seems that there is no other option as standard. Web developers can only offer their own ideas to hide the place where a password is stored before the request.

Encryption – How do biometric password managers work?

Many mobile password managers offer the ability to unlock the password safe with a fingerprint instead of a password. If you never type your master password, how is it possible to decrypt the data? It seems that there is a way to decrypt the database without typing the master password.

How can I see if my user's password has expired in MySQL?

New in programming, you have to do it for a job. You can not find anything in google or notes. Thank you. The version is 8.0.16

Encryption – Why does AWS distribute a private key for authentication without a password?

AWS provides access to EC2 by downloading the private key (.pem) as a management host that connects to EC2.

AWS uses openssl tool

Key providers generally provide a public key but not a private key, because with key pairs, one can encrypt with a public or private key and decrypt with another key, as shown below:

$ openssl genrsa -out mykey 2048

$ cp mykey privatekey

$ openssl rsa -in mykey -pubout -out publickey 

$ rm mykey

$ # Encrypt with public key

$ echo "the cat sat on the mat" | open ssl rsautl -encrypt -pubin -inkey publickey > ciphertxt

$ # cat cipher.txt

$ # cat cipher.txt | openssl rsautl -decrypt -inkey privatekey 

Why does AWS distribute the private key instead of the public key? for secure communication …

The key pair is primarily used to secure communication over the network, but not to authenticate the user, to access a resource in AWS.

ssh -i something.pem user@ec2-public-dns-name

How does the distribution of a key solve the authentication problem? Anyone can steal the key … Why does AWS allow the SSH connection to EC2 without a password?

Password management with a password always hidden

Is there a password management application that permanently hides the password of a non-administrator user, even at auto-completion on a web browser?
The idea is to keep the password protected users, they could simply copy to the clipboard and paste it only on a secure field. This prevents users from writing or otherwise storing the password.
And this application should work with iOS, Android, Windows and MacOS.

wi fi – recover Android Pie WiFi password file

I know that Android (at least Pie) uses a WifiConfigStore.xml file to store WiFi access points and passwords. It is in / data / misc / wifi /.

I have saved it before erasing and reinstalling everything. The idea was to copy it to this place. When the phone is on / on, it appears that the information in this new file is not being used. But after rebooting, he left and crashed.

So my question: Is there something special? Or is not it the right place? Is a backup file stored elsewhere?

(I have a LineageOS 16 device rooted with Magisk.) I've even tried modifying the file in TWRP without getting a better result.)

Edit: Found that this file is also located in
/ data / misc_ce / 0 / wifi,
/sbin/.magisk/mirror/data/misc/wifi and

And there are also files
WifiConfigStore.xml.encrypted-checksum. Naming it looks like that, including a checksum to avoid errors in the XML?
This file I did not save. Am I lost now? Can I delete this and it will be created that?

What is the function of these misc_ce folders?

Thank you!
