Your Bitwarden password vault can be accessed from the browser extension. After installing the extension, there will be a Bitwarden icon in the toolbar at the top of the browser window.
Click on the Bitwarden icon in the browser toolbar
Navigate to the My Vault tab and select the + Add icon
Select Login from the dropdown
If you're adding a card, identity, or secure note instead, select that type instead
Enter a Name for the item
Names will help you easily identify items in your vault, so give this item a recognizable one (e.g. My Twitter Account)
Enter your Username and Password
For now, enter your existing password. We'll help you replace it with a stronger password later
In the URI 1 field, enter the URL of the website (e.g. https://twitter.com/login)
If you don't know what URL to use, navigate to the website's login screen and copy it from your address bar
From the Folder dropdown, select the name of the folder you want to add this item to
Folders can be created with + button in the left sidebar on the main page
Click the Save button to finish adding this item
Now that you've saved a new login, let's improve its security by replacing your password with a stronger one:
In your web browser, login to the account with your existing username and password. In that account, find where you can Change your password
On the Change your password form, enter your Current Password, which you can copy and paste from Bitwarden using the Copy icon.
Back in Bitwarden, open the login item and select the Edit button
In the Password box, select Generate and select Yes to overwrite your old password. This will replace your password with a randomly-generated strong password
Moving from Fido1234 to X@Ln@x9J@&u@5n##B can stop a would-be hacker in their tracks
Select Save
Copy your new password and paste it into the New Password and Confirm Password fields back on the website
