How to use Skype without an account

Skype Web

Before explaining in detail how the classic version of Skype works , I want to point out the possibility of using the service without registration and without installing programs on the PC , acting directly from the browser (provided that you use one of the supported navigation software, i.e. Chrome and Edge ).

By connecting to this web page and clicking on the Create a free meeting button , you can create a chat room to share with anyone who wants to join your video conference. The link to the room will be shown to you within a few seconds: you can then copy it (by clicking on the icon with the two sheets), share it (by clicking on the appropriate button) or start the call (by pressing the appropriate button). It should be noted that the link does not expire and can therefore be used at any time.

Once you have visited the address of the conference, anyone can join by simply clicking on the Join as guest button and setting a username or logging in with a Skype account (optional). It should be noted that guest accounts (those created by putting only the name and without logging on to Skype) expire after 24 hours.

For the rest, there is not much to add, as the interface of this web version of Skype is very intuitive: at the bottom there is the chat field , with the buttons next to it to send attachments, invite contacts, create polls etc. while at the top right there are the buttons to start / join the call (you can choose whether to activate the camera and / or microphone and you will have to allow the site to access these components) and leave the group .

Once the video call has started, you will find in the lower center the buttons to adjust the microphone / camera and hang up, on the left the button to start recording the conversation and on the right the buttons to open the chat , share the screen , send a reaction etc.

How Skype works on a computer

When you start Skype for the first time,  you need to log in, as you need a Microsoft account in order to use this VoIP application.

If you start the application on Windows , you may be prompted to log in with the Microsoft account associated with your computer; alternatively, use the text field in the center to log in or create a Microsoft account. If you need a hand to carry out the registration procedure, you can also read my tutorial dedicated to the subject.

Once logged in, you need to perform audio verification and video verification to test the webcam and microphone. Then you have to accept that the contacts of your Microsoft account are automatically synchronized with Skype and press the OK button , to access the main Skype screen.

The contacts in your Microsoft account will be automatically synchronized and will be visible in the Contacts section on the left. The contact icons are marked with colored dots: the green one indicates that the user is online on Skype and available for conversation, the yellow dot indicates that the user is not at the computer, while the red dot determines that the user is busy and will not receive notifications about conversations.

To set your Skype status click on your photo from the top bar and then on the item relating to the status you want to set (eg Available ) from the menu that opens. In addition there is the Invisible option , which is used to use Skype without showing yourself online to contacts.

The other useful functions of Skype concern the addition of a contact, a procedure necessary for sending messages to a person, which can be carried out by pressing on the Contacts item from the sidebar, then on the wording New contact and finally on Search in the directory of Skype . Then, using the text field located in the left sidebar, type the name of the person you want to add to Skype and, once identified, press the Add button you see on the screen.

You can also send multimedia content and documents, by pressing the button with the photo symbol respectively , corresponding to the chat. Instead, press the button with a microphone symbol to send an audio message to the selected user.

The other interaction tools are the button with the symbol of a business card and the symbol (…) which, respectively, allow you to send the contact of another user and to share positions , video messages , surveys , money , OneDrive links. o Spotify and more.

Optionally, you can also invite a third person to join the conversation you have active with a user. To do this, press the button with the symbol of a little man you see at the top of the chat and then, select, from the drop-down menu, the contact to add by clicking on his name and then pressing the Done button .

Skype also gives the possibility to make calls and video calls over the Internet to users of the platform but not to landline or mobile numbers (for the latter options it is necessary to purchase Skype credit or to subscribe to a subscription, with prices starting from 3.66 € per month).

To start a call or a video call on Skype , click on the user’s name from the Contacts section (on the left), then press the button with the symbol of a video camera (for the video call) or on the button with the handset symbol (for the voice call).

Once the connection is started, there are the buttons with the symbol of a video camera (used to activate and deactivate the video camera and activate the background blur), the one with the symbol of a microphone (used to activate and deactivate the microphone), the symbol …  allows you to display a menu of shortcuts ( Start recording , Enable subtitles , Perform background blur , Disable incoming video , Put the call on hold and Audio and video settings ), the button with the speech bubble allows you to call up the text chat, while the one with the square(bottom left) allows you to create a snapshot.


In addition, on a computer, it is also possible to use Skype for Web , an online version of the software whose use is very similar to the desktop version.
