+
+### Sending a password
+  1. 1. Go to [Privatebin @ LCSB](https://privatebin.lcsb.uni.lu/) and type the password you want to share into the Editor tab. You will be asked to enter your LUMS credentials when you click on "Send"<br/>

+  
+  1. Set expiry period
+    -  For the highest safety measures, sender can allow password link to be used only once so it expires upon first access. This feature can be set by checking **Burn after reading** checkbox.  
+    
+  1. You can also enter a password to protect your password link - this should be **different** from the password you are sharing!
+  1. Click **Send** in right-top corner
+    - you should be redirected to a page containing the password and password link 
+    <img src="privatebin-link.png"><br/>
+  1. Share the **link** with your collaborator via your favorite communication channel
+
+### Receiving a password
+  * You have been provided a link to website where your new password is stored. (This link can be protected by yet another password you might be asked to enter.)

+
+  * If you see following:
+<img src="privatebin-expired.png"><br/>
+    * You have either entered the wrong/incomplete link - try copy-pasting the link into your browser instead of clicking on it - or
+    * your password link has already expired. In that case you will have to request a new link.<br/> 
+      **Warning!**: If the password link was set with one access only (**Burn after reading**) and you are sure that you haven't accessed the link so far, you should notify the password sender because there is a chance that your communication was intercepted and someone accessed the link before you.<br/>
+      **Note**: If the page looks different from the pictures above, try using Google Chrome browser. If the issue persists, please take a screenshot of the page and send it to our [sysadmin](mailto:lcsb-sysadmins@uni.lu) team.
