How to Stay Safe?
Currently, LastPass has confirmed that it is working to fix the security issues with their service and a full fix can be expected soon. In the meantime, it’s recommended for LastPass users to heed to the following precautions.
- To safeguard their login credentials, users are recommended to disable the browser extensions in the meantime and launch websites directly from the LastPass Vault until the vulnerabilities are resolved by the company.
- Turn on Two-Factor Authentication for all the accounts that offer the option, giving your account an added layer of security in case the vulnerability is exploited by an attacker.
- Be on a lookout for phishing attacks. Do not click on links from untrusted sources — people you don’t know
