Password security¶
How Weblate stores passwords¶
Weblate uses a Django implementation to store hashed passwords; see How Django stores passwords.
The recommended Weblate configuration uses Argon2 with time_cost = 2, memory_cost = 102400, and parallelism = 8.
Sugestie
The password hashing can be customized using PASSWORD_HASHERS.
Password validation¶
When a user is configuring a password, it is validated to reduce the risk of using weak passwords.
The recommended Weblate configuration verifies:
The password has to be at least 10 characters long, and at most 72 characters long.
Password similar to username and other attributes is rejected.
A common or overly simple password is rejected.
Any password user used recently is rejected.
Password strength is optionally checked using the zxcvbn algorithm.
Sugestie
The password validation can be customized using AUTH_PASSWORD_VALIDATORS.
Social or third-party authentication¶
Weblate does not store any passwords or enforce any password policy when social or third-party authentication is configured. The passwords are, in such a case, fully managed externally.
