Multi-factor authentication is critical for secure business portal access. Time synchronization issues between authentication devices and servers are among the most common problems preventing successful login. This guide addresses time skew issues for both hardware tokens and mobile authentication apps.

Understanding Time-Based Authentication

Time-Based Authentication Fundamentals

  • TOTP Mechanism: Time-based one-time passwords rely on synchronized clocks
  • 30-Second Windows: Each code typically remains valid for a short timeframe
  • Drift Tolerance: Systems usually accept small time differences (±90 seconds)
  • Resync Requirement: When drift exceeds tolerance, authentication fails

After completing CashPro login, time-based authentication provides an essential security layer that protects your session even if your password is compromised.

Identifying Time Synchronization Problems

Watch for these symptoms that typically indicate authentication time issues:

  • Consistent Code Rejection: Multiple correctly-entered codes are rejected
  • "Invalid Code" Messages: Even when codes are carefully entered
  • Inconsistent Results: Authentication sometimes works, sometimes fails
  • Quick Session Timeouts: Successful logins expire unusually rapidly

Hardware Token Solutions

Hardware Token Time Drift Facts • New tokens: ±2 seconds/month drift • 1 year old tokens: ±5 seconds/month • 2+ year tokens: ±10+ seconds/month • Failure threshold: typically ±90 seconds

User Resynchronization Steps

  1. Contact your administrator about token synchronization issues
  2. Provide your token's serial number (usually on back of device)
  3. When requested, generate two sequential codes
  4. Wait for admin confirmation of successful resynchronization
  5. Test with a new code to verify the fix is working

Administrator Procedure

Admin Resynchronization Steps
  1. Access the administration portal and navigate to token management
  2. Locate the user's token by username or serial number
  3. Select the resynchronization function
  4. Collect two consecutive codes from the user
  5. Enter both codes in sequence and submit
  6. Have the user verify successful authentication

If multiple resynchronization attempts fail, the token likely needs replacement.

Mobile Authentication App Fixes

Mobile app time synchronization issues are typically easier to resolve:

Basic Time Alignment Steps

  1. Enable Automatic Time:
    • iOS: Settings → General → Date & Time → Set Automatically
    • Android: Settings → System → Date & Time → Automatic
  2. Force Time Update: Toggle airplane mode on/off to trigger time server check
  3. Verify Timezone: Ensure correct timezone for your location
  4. Update App: Install the latest version of your authentication app

Important Security Warning

Never attempt to modify or tamper with authentication tokens. Improper manipulation can damage tokens or trigger security lockouts. After CashPro login issues, always follow authorized procedures for resolving authentication problems.

Preventive Measures

Hardware Token Maintenance

  • Proactively resynchronize tokens every 3-6 months
  • Track token age and replace batteries before depletion
  • Protect tokens from extreme temperatures
  • Plan for token replacement before end-of-life

Mobile App Best Practices

  • Always use automatic time settings
  • Keep authentication apps updated
  • Before international travel, verify automatic timezone settings
  • Configure backup authentication methods when possible

Enterprise Time Management

Large organizations should implement these administrative controls:

Control Area Implementation Recommendations
Token Management
  • Track token inventory, age, and synchronization history
  • Perform scheduled verification tests
  • Implement proactive replacement programs
Time Infrastructure
  • Deploy internal NTP servers synchronized to authoritative sources
  • Enforce device time policies through IT management
  • Use MDM solutions to control mobile device settings
User Preparation
  • Train users to identify and address time issues
  • Establish clear problem reporting procedures
  • Provide travel authentication guidance

Key Implementation Principles

Time synchronization is essential for reliable multi-factor authentication. Address issues promptly by following the appropriate procedures for your token type. Implement preventive measures to avoid future problems, and establish administrative controls to manage authentication enterprise-wide. Following CashPro login best practices ensures your financial operations remain secure and accessible.
