Hi! I understand your main password isn’t working after updating Memento Database to version 3.6.0. Let's get this sorted out together.

First, just to clarify:
1. Are you certain the password you entered before the update is the correct one?
2. Did you have multiple libraries protected by this password?
3. When exactly did the problem start — immediately after the update or sometime later?
4. Are you seeing any error messages when you try to enter the password?

Sometimes, after an update, password or library encryption settings may require a reset or there might be a change in how the app manages protection.

Here are some steps we can try:

1. Restart the app and your device. This clears temporary glitches.
2. Check for any app notifications or prompts related to password changes after the update.
3. Try the 'Reset the master password' option if available in Settings > Protection or Library menu. Be aware, resetting may remove password protection, but it won’t recover a forgotten password if you’ve lost it.
4. If you had enabled library encryption, you can check the Library menu under Protection settings to see if you can disable or reconfigure the password there.
5. Verify the update installed correctly. Sometimes, reinstalling the update can help with unexpected bugs.
6. Check if you have a backup of your database or libraries. If so, restoring from a backup before the update could allow access again.

If none of these steps restore access, it may help to reach out directly to Memento Database support at [email protected] with details of your issue and any error messages.

Could you tell me what you’ve already tried or noticed? This will help me guide you better and avoid repeated steps.

Are you able to access the app at all, or is the password prompt blocking entirely?
