FAQ
What is password manager switching risk?
It is the chance that a migration causes missed shared vaults, weak reused passwords, broken 2FA recovery, lost emergency access or confusion for family or team members.
Does this calculator choose between 1Password and LastPass?
No. It scores migration complexity and links to Omellody comparison pages so you can verify current vendor security, pricing and feature terms.
Should I delete my old vault immediately?
Usually no. Keep an export or old account only as long as needed for a safe migration, then follow official vendor guidance for deletion and account closure.
Is this security advice?
No. It is educational decision support, not personalized security, legal, insurance or compliance advice.
