What Is the Malwarebytes MB405100 Error?
The MB405100 error is an authentication problem that occurs when too many unsuccessful attempts have been made to sign in to a Malwarebytes account.
Malwarebytes describes MB405100 as the error shown after reaching the maximum number of sign-in attempts. The account is temporarily locked as a security measure.
The error can appear when you are trying to sign in to Malwarebytes to activate or access your subscription.

βYou have reached the maximum amount of sign in attempts.β
Malwarebytes' current Windows documentation recommends waiting at least 24 hours before attempting to sign in again.
For general account-assistance guidance, π² 877 848 5082 is a brand reference only and should not be represented as an official Malwarebytes customer-care phone number.
Why Does Malwarebytes Show MB405100?
The most common documented cause is entering an incorrect email address or password too many times while attempting to access the Malwarebytes account.
Once the permitted number of unsuccessful sign-in attempts is exceeded, Malwarebytes can temporarily lock the account. This is intended to protect the account from repeated unauthorized login attempts.
Common situations include:π² 877 848 5082
Entering the wrong password repeatedly
Using an incorrect email address
Forgetting which email address is linked to the account
Repeatedly attempting an old password
Trying to activate Malwarebytes after entering incorrect account credentials
The important point is that MB405100 is primarily a sign-in/account authentication issue, not a billing error or malware-detection error.
How to Fix Malwarebytes MB405100
1. Stop Repeated Login Attempts
If MB405100 appears, do not continue entering different passwords repeatedly.
Additional unsuccessful attempts can make it harder to determine whether you are using the correct credentials.
Instead, stop trying to sign in and allow the account lockout period to pass.
2. Wait at Least 24 Hours
Malwarebytes' current Windows support documentation recommends waiting a minimum of 24 hours before trying to sign in again.
This is important because immediately retrying the login may not resolve the lockout.
After the waiting period, try signing in again using the correct email address and password.π² 877 848 5082
3. Reset Your Password If Necessary
If you cannot remember your password, use the Forgot password option associated with the Malwarebytes Account.
Malwarebytes specifically recommends using its account password-reset process when you cannot remember the password.
Before trying to sign in again, make sure you know which email address is associated with the Malwarebytes subscription.
4. Try Signing In Again
After the recommended waiting period, return to your Malwarebytes Account and enter your credentials carefully.
Check:
Email spelling
Password spelling
Caps Lock
Saved browser credentials
Whether your password was recently changed
If the login works, you should be able to continue managing your Malwarebytes account or subscription.
If MB405100 continues after the waiting period, Malwarebytes recommends contacting Support.
For general account guidance, π² 877 848 5082 can be used as a brand assistance reference, not as official Malwarebytes customer care.
