Start with the SeleID Security Center. It brings the available password, two-step, passkey, recovery and access controls together. Read the current status beside each protection instead of assuming that opening its screen switches it on.
Make your first checks
Confirm the email belongs to you and remains accessible. Use a password you do not use on another service. Open Password if you need to change it; the current form asks for your existing password, the new password and confirmation. Follow the displayed requirements and wait for a successful result.
Add supported protections
Read two-step verification and passkeys before setting them up. Availability depends on your installed app and phone. Complete the confirmation challenge when offered, and keep any recovery codes private. A fingerprint unlock for an already signed-in app is different from a passkey that signs you in.
Review access
Use Session Management to find the logout controls, and check Connected Apps for services you authorised. If a status cannot load, treat it as unavailable information rather than proof that your account is safe.
Respond to a concern
If someone may know your password, change it from a trusted device and end other sessions using the available controls. Do not send passwords, verification codes or recovery codes to anyone. Read scams and phishing and losing your phone for practical next steps.
