I cannot sign in
Diagnose failed sign-in, password issues, and MFA challenges.
What it is for
Most sign-in problems come from an unconfirmed email, a wrong password, or an extra authentication challenge the UI cannot complete.
When to use it
- Sign in returns an error
- You are stuck after Create account
How to do it
Step 1 — Confirm the email
If you just signed up, complete Confirm your email with the verification code before Sign in.
Step 2 — Reset the password
Use Forgot password? → Send code → Update password, then Sign in.
Step 3 — Read the error text
Messages such as MFA or challenge mean an extra step is required outside the simple form. Password too short means you must meet the policy.
Good to know
- Use the same email you confirmed at signup.
Common problems
Sign-in keeps failing after a correct password.
Reset the password with Forgot password?, confirm your email if needed, then try Sign in again. If it still fails, note any error text and contact your account administrator.
Didn’t find a solution?
If the problem persists, note any support ref shown in an error message in the app, and share it with your administrator. Protegon does not display a separate support contact form in the product.
