Overview
Asaph uses passwordless authentication through one-time codes sent to your email. No password to create, remember, or reset—just request a code and you're in.
What Are One-Time Codes?
One-time codes are temporary numeric codes sent to your email address. Each code works only once and expires after 15 minutes. Think of them as temporary passwords that arrive in your inbox.
Why Passwordless?
No Password to Remember
You'll never forget your Asaph password because there isn't one. No password manager needed.
No Password to Steal
Hackers can't steal a password that doesn't exist. Your email account's security protects your Asaph access.
Automatic Expiration
Every code expires after 15 minutes. Old codes become useless, preventing unauthorized access even if someone sees an old email.
One-Time Use
Each code works only once. Even if someone sees your code, it won't work after you've used it.

Security Benefits
Email-Based Security
Your email account's security (password, two-factor authentication) protects your Asaph account. Keep your email secure to keep Asaph secure.
Time-Limited Access
Codes expire quickly, giving you a short window to use them. This prevents misuse of old codes.
Fresh Code Every Time
Request a new code for each login session. Each one is unique and can't be reused.
Multiple Devices
Same Process Everywhere
Request a code on your phone, tablet, or computer—it works the same way everywhere. Enter the code on the device where you want to log in.
Staying Logged In
Once you enter a code and log in, you stay logged in on that device. You don't need a new code every time you open Asaph—only when you log out or your session expires.
Each Device, One Login
Request a code on each device you use. Your session stays active on that device until you log out. You can access Asaph from your laptop, phone, and tablet simultaneously—just request a code for each device once.
Best Practices
Keep Your Email Secure
Use a strong email password and enable two-factor authentication on your email account. Your email security is your Asaph security.
Don't Share Codes
One-time codes are personal login credentials. Don't forward them to others or share them in messages.
Request Fresh Codes
Don't try to save or reuse old codes. Request a new one each time you need to log in.
Use Recent Codes First
If you requested multiple codes, use the most recent one. Older codes may have expired.
Common Questions
What if someone else gets my code?
They would need access to your email inbox. If you're concerned, log out of Asaph and change your email password immediately.
Can I use the same code twice?
No. Each code works only once. After you use it, request a new code for your next login.
Do codes work offline?
No. You need internet connectivity to receive the email and log into Asaph after entering the code.
Can I save a code for later?
Don't bother. It expires after 15 minutes and only works once. Always request a fresh code when you need to log in.
Why can't I just use a password?
Passwordless authentication is more secure and convenient. You can't forget or lose something you don't have.
