There are a few common reasons for login trouble: a forgotten password, a security lock, or a browser issue. Here's how to fix each one.
I forgot my password
How to reset your password:
Go to the Prolific login page
Click “Forgot password?”
Enter the email address linked to your Prolific account
Follow the instructions in the password reset email
Note: New passwords can take up to 10 minutes to activate. Please wait before logging in again.
I didn't receive the password reset email
If the email doesn't arrive within a few minutes:
Check your spam or junk folder
Search your inbox for [email protected]
Make sure you entered the correct email address
If you still don't receive the email, contact us using the chatbot icon in the bottom right of your screen, we'll check your account and email delivery.
Closed accounts don't receive reset emails, and closure is permanent.
I no longer have access to my email address
If you can’t access the email linked to your Prolific account (for example, an old institutional email), we’ll need to verify your account and update it manually.
Contact us using the chatbot icon in the bottom right of your screen.
I can’t get passed multi-factor authentication (MFA)
If you're having trouble accessing your authentication app, click the "Try another method" link at the bottom of your screen. There, you'll need to enter the recovery code you received when you first signed into the authenticator app.
If you don't have your recovery code or are still experiencing problems, please get in touch with our support team.
For more information, see Multi-factor authentication (MFA)
Account temporarily locked or on hold (PEC-AS-0006)
A PEC-AS-0006 error means we've temporarily locked your account for security. Contact us using the chatbot icon in the bottom right of your screen to get it reviewed and unlocked.
Common triggers include:
Multiple failed login attempts
Mistyped email or password (often from autofill)
Using a VPN or proxy
Automated security checks
Once you're back in, double-check your login details, turn off any VPN or proxy, and make sure your browser isn't autofilling something wrong.
reCAPTCHA error (PEC-AS-0005)
This error means our system couldn’t confirm you’re a human rather than a bot.
Try the following:
Use a different browser (Chrome, Firefox, Edge, Safari)
Try a different device
Turn off ad blockers or privacy extensions
Disable browser extensions temporarily
Restart your router (if on Wi-Fi)
Run an anti-malware scan, as malware can sometimes interfere with reCAPTCHA checks
If the error persists, contact support so we can investigate further.

Password managers

Re-enter your login details manually
Update the saved entry in your password manager
Time and date settings
For security reasons, your device’s date, time, and timezone must be accurate.
