Manage Your Security Email Address for LastPass
Depending on your security settings, LastPass may occasionally email you security notifications that require your response, which are sent to your primary LastPass username (email address). However, you can further safeguard your account by adding a secondary security email address to which security notifications can be sent in case your primary account email address is ever compromised.
Warning: If you have a LastPass Business account, updating your email address may invalidate your existing sign-in configurations. Before proceeding, please contact your LastPass admin.
Results: You have added a new security email address for your LastPass account.
