Logins

Breaking Changes

• The Android bindings now collect some basic performance and quality metrics via Glean.
  Applications that submit telemetry via Glean must request a data review for these metrics
  before integrating the logins component. See the component README.md for more details.
  (#2225)
• username, usernameField, and passwordField are no longer
  serialized as null in the case where they are empty strings. (#2252)
  • Android: ServerPassword fields username, usernameField, and
    passwordField are now required fields -- null is not acceptable,
    but empty strings are OK.
  • iOS: LoginRecord fields username, usernameField and
    passwordField are no longer nullable.
