This article covers: not receiving a sign-in code, unrecognised email or phone number, account lockout, company sign-in (SSO) issues, changed contact details, and missing invite.

Find your issue below and follow the steps to resolve it.

📵 I didn't receive my sign-in code (OTP)

Wait up to 60 seconds - codes can be delayed by your mobile network or email provider
Check your spam or junk folder if you requested a code by email
Tap Send again in the app to request a new code
Make sure you're entering the exact phone number or email address your employer registered you with - including the correct country code for phone numbers
If you've tried several times without success, see the full guide: What to do if you didn't receive your 6-digit login code

❓ Blink doesn't recognise my email or phone number

Try both options - if you tried Continue with email, also try Continue with phone (or vice versa)
If you sign in via your company's single sign-on system (SSO), enter your work email address exactly as it appears in your company directory
If you're still not recognised, your account details are held in your employer's HR or IT system - contact your manager or IT/HR team to confirm which email or phone number is registered

🔒 I've been locked out after too many attempts

Blink limits sign-in attempts to protect your account:

30 attempts per day - your daily limit resets each day at midnight
100 attempts per month - your monthly limit resets at the start of each calendar month

If you've hit your daily limit, wait until the following day and try again. If you've hit your monthly limit, contact contact Blink support for assistance.

🏢 My company or work sign-in isn't working (SSO/SAML)

Single sign-on (SSO/SAML) is managed entirely by your employer's IT team - Blink has no control over it. If your company sign-in is failing:

Check whether your corporate password or SSO session has expired and needs to be renewed
Try signing in via your employer's intranet or another SSO-connected app to confirm your access is working
If other SSO apps work but Blink doesn't, contact contact Blink support - include your company name and the error message you're seeing
If SSO has stopped working for multiple people at your organisation, escalate to your IT team

✏️ My email address or phone number has changed

Your Blink account is linked to the contact details in your employer's HR system. Blink automatically syncs from that system, so you cannot change your sign-in details in Blink directly.

Ask your HR or IT team to update your email address or phone number in your company's HR system
Once updated, the change will sync to Blink automatically - the timing depends on your employer's sync schedule
If the sync has happened but you still can't sign in, contact contact Blink support

📧 I'm trying to sign in but I haven't received an invite

You need to accept your invite before you can sign in. Check your email (including spam) for an invite from Blink, or ask your manager to resend it. See: Accepting your invite to Blink.

❓ FAQs

I keep getting signed out - why?

This can happen if your employer's security policy enforces session timeouts, or if you've signed in on a new device. It can also happen after an app update. Check your notification settings to make sure Blink has permission to run in the background on your device. If you're regularly being signed out without explanation, contact contact Blink support.

I'm getting an error message I don't understand - what should I do?

Take a screenshot of the error and contact contact Blink support. Include your full name, the device you're using, and the steps you took before the error appeared.

My issue isn't listed here - what should I do?
