bitcoin core – Password before complete transaction

I was about to spend some bitcoins but Bitcoin Core required my password, which I don’t remember, to complete transaction… The wallet is open but cant use bitcoins.

I would like to know if before ANY transaction, you must ALWAYS enter password. This is the first time I try to send bitcoins so I don’t know how this goes…


db2 10.5 – How can I add a user and specify a password for a in IBM Data Studio?

In Data Studio I can connect to a sever/database, go down to Users And Groups, right-click on Users and add a new one. But the program never asks me for a password. How can I specify it?

Also, no matter how many times I tried to “Save changes” they are never saved. I even tried to “generate change” and run it, but it always fails.

I am connecting as the only user that exists on the server: db2admin. If db2admin has no authority to manage users, then who has?

ios appstore – iPhone App Store: can I install free apps using Face ID instead of my Apple ID password?

The App Store prompts me for my password for every free app I am trying to install. I have already Face ID setup, can I use it instead? Or even the phonr’s passcode?

I have a Macbook where I’ve disabled the password prompt for free apps, but I’m not sure whether that’s device specific.

I have tried restarting the phone and disabling Face ID for the App Store.

iOS 14.1

How can I create a user that is not allowed to change its own password on mediawiki?

I am currently creating a mediawiki where there are administrators and writers, and everyone else in the project only needs read access. Our current approach is having all the read-only users share a same login for accessibility. How can I ensure that this user is not able to change its own password?

lightning network – Can we use lnurl-auth to create a better password manager?

LNURL-auth can be used to implement registration/login in a web app in which users don’t need username/password or other credentials instead they can just use their LN wallet to login. However cannot be used if the website doesn’t support it so can we do this locally for websites using a browser add-on?

Right now only few websites support it including LNMarkets

I have also created an issue in btcpayserver repository to support it:

How would LNURL-auth work with a password manager?

When you create a new password, the password manager uses the main lnurl-auth key to derive a key specific for that password(challenge: random value), uses that key to sign the challenge and then saves both the public key specific for that password plus the signed challenge locally.


When the user needs to login using one of the saved passwords in a website, scans a QR code shared by password manager browser add-on or enters some PIN used by internal LN wallet in pwd manager, it retrieves the public key, checks it against the challenge signature and attempts login for that user.

What are the pros and cons if this is possible?

I don’t understand the below part mentioned in this link:

In fact, lnurl-auth is very unique in the sense that it doesn’t even need a Lightning wallet to work, it is a standalone authentication protocol that can work anywhere.

Also I don’t know why linking LN wallet on requires user to pay 100 sats invoice. Is it added to avoid spam registrations?


I was not asked to pay anything to login on



ubuntu – SSH/SCP with public key AND password authentication SIMULTANEOUSLY

The server I’m attempting to SCP a file to requires BOTH a password AND a public/private key. I’m trying to send the file from Ubuntu but I can only get scp to use either key OR password, but not both. If I have the public key in place then scp never prompts for a password, authenticates successfully, then the server drops the connection because no password was provided. Likewise, if the key is not present I get prompted to enter a password, authentication is successful but the server drops the connection because there’s not a private key.

I can successfully login to the server using WinSCP by configuring a password AND key, I just can’t figure out how to do this from Ubuntu.

If it matters, the server in question is ws_ftp running on Windows Server 2008.

password manager recommendation – Android Enthusiasts Stack Exchange

I have a password manager called keepass installed on my laptop. I really like the feature of autotyping. But it cames to a android I have installed KeePassDx it is really annoying for me to unlock the database search for the entry a want, copy username, go to the browser, put the username, then go back to the app, copy the password, again go to the browser and paste it.
Is another method less painful, with less steps to do this?

imac – Wiped all disks for Ubuntu installation, but “macOS Recovery over the Internet” still knows my Wi-Fi password

I wiped all disks for Ubuntu installation. The macOS Recovery partition was gone.

Decided after half of an year, to install again macOS with macOS Recovery over the Internet

If you can’t start up from macOS Recovery

If your Mac can’t start up from its built-in macOS Recovery system, it
might try to start up from macOS Recovery over the Internet. When that
happens, you see a spinning globe instead of an Apple logo during

enter image description here

I was very much surprised the this “macOS Recovery over the Internet” knows my Wi-Fi password.

He didn’t ask for password and begin download stuff off the internet.

Can you explain why he remembers my Wi-Fi password?

I supposedly shared my Instagram password with an illegal service

After entering to, I get the following message:

Your Account Was Compromised

It looks like you shared your password with a service to help you get more likes or followers, which goes against our Community Guidelines.

Change your password to continue using Instagram. If you share your new password with one of these services, you may get blocked from following, liking or commenting.

However, I never shared my password with any such service. In fact, I don’t even have an Instagram password.

Before getting this error message, I regularly got alerts about “suspicious activity”, and it had me confirm my phone number or email address.

I was able to restore my account, but I’m wondering why Instagram sees “suspicious activity” or that I “shared your password with a service to help get more likes or followers”.

Some details Instagram may see as suspicious:

  • I have visited one such website, but out of curiosity, and never inputted my password or account details. I use the Brave browser, so Facebook shouldn’t be able to track me out of Facebook.
  • I use Linux.
  • I have a rooted Android phone.
  • I’ve used the browser developer tools on Instagram.

python – Password strength checker (Udemy course)

This program is a project out of Udemy course. Kindly request you to review my code and suggest insights to better it. It takes your password hashes (sha1) and then sends hashedpassword(:5) to website. Gets the response and checks whether our hashed password is present in the response got from the site

Thanks in advance!!
