| Symptom | Likely cause | First safe fix |
|---|---|---|
| Login loop | Cookies or redirects blocked | Allow cookies and clear site data |
| Blank page | Script or extension conflict | Test private window and disable extensions |
| Works in one browser only | Browser-specific cache or policy | Use updated browser and check settings |
Clean browser test
A clean browser test helps isolate the problem without changing account settings.
- Open private/incognito mode.
- Navigate from official Synovus pages.
- Try the same login once.
Cookies, redirects and pop-ups
Secure portals can rely on cookies, redirects, and sometimes secondary windows. Blocking all of them can break login.
- Allow necessary cookies.
- Allow pop-ups only for official domains.
- Avoid global “allow all” settings.
Extensions and managed policies
Ad blockers, script blockers, privacy tools, password tools, and corporate policies can change page behavior.
- Disable extensions temporarily for testing.
- Ask IT about managed browser restrictions.
- Avoid installing unknown “fix” extensions.
Use official Synovus help for account-specific issues
For login access, account-specific changes, locked users, payment services, fraud concerns, or confidential banking questions, use official Synovus channels. Start at the official Synovus website, review the official Synovus Gateway information page, or use the official Synovus contact page.
Do not share codes or passwords
No help guide, phone caller, email sender, text message, or “support agent” should ask you to share your banking password, one-time access code, full account number, card number, or remote computer access. Stop and verify through official channels.

FAQ
Does clearing cache delete bank data?
No. It removes local browser data, not your bank account. Be careful with saved passwords.
Can extensions break login?
Yes. Script blockers and privacy extensions can interfere with authenticated pages.
What if my company manages my browser?
Ask IT to test policies, extensions, and network filters.
