Two-factor authentication adds a second step to signing in: as well as your password, you enter a one-time code emailed to you. That way, someone who learns your password still can't get into your account.
How it works in Ask A Vet
Two-factor authentication is off by default and you switch it on yourself in Settings → Security, using the Two-Factor authentication toggle.
The setup screen says it clearly: "Add an extra layer of security to your account."
The method available
Ask A Vet currently offers one method:
- Email — "Receive a verification code via email for added security."
Important: codes are always sent to the email address registered on your account. Make sure you can still receive mail there before switching it on.
Please note: [CONFIRM: whether text-message (SMS) two-factor authentication will be offered to pet owners]
What signing in looks like afterwards
- Enter your email and password on the Login screen and tap Log In.
- Ask A Vet emails a code with the subject "Your Ask A Vet sign-in code" and opens the Verify your email sheet.
- Type the 6-digit code and tap Verify. You're in.
The sign-in email also carries a useful warning: "Didn't try to sign in? Someone may know your password. Reset it right away from the Ask A Vet app."
Two behaviours worth knowing
| Behaviour | What it means |
|---|---|
| A new code is only created when you sign in without one | Entering a wrong code does not trigger a fresh email — tap resend to get a new one. |
| New codes are limited to one every 30 seconds | The Resend OTP link stays disabled and counts down until then, and asking sooner won't produce a new code. |
Both are deliberate, to stop someone flooding your inbox with codes.
Important: there are no backup codes. If you lose access to your account's email inbox you won't be able to sign in, so keep that address reachable. [CONFIRM: the support process for a customer locked out of their two-factor email]
